+ between collection of elements. When collection differ, the tester is

+ elements.

+module EInt =

+ type t = int
+ let compare = ( - )

+ [1; 2; 5; 4]
+;;
+
+let _ =
+ run_test_tt_main ("test_diff" >:: test_diff)
+;;
+]}
+
+when run this test outputs:
+{[
+OUnit: expected: 1, 2, 3, 4, 5 but got: 1, 2, 5, 4
+differences: element number 2 differ (3 <> 5)

(* We're dealing with the tensor algebra freely generated by
momenta, metric and $\epsilon$ tensors, as well as scalars,
vectors and tensors constructed from fermionic bilinears.
The design problem that we're dealing with is that an implementation
relying on types to guarantee that only legal expressions can be
constructed will be hideously complex. A ``correct'' solution would
represent vertices as tensors, without using indices, external
polarization vectors or currents. However, the presence of
contractions~$g^{\mu\nu}$ and~$\epsilon^{\mu\nu\rho\sigma}$ introduces
a wealth of special cases, corresponding to which combinations of invariant
tensors remains uncontracted.
Therefore, it appears to be a better strategy to use arithmetic expressions
built from tensors contrated with external polarization vectors. We can then
check at runtime that the expression is linear in these polarization vectors. *)

\caption{\label{tab:P(n),F(n)}
The number of $\phi^3$ Feynman diagrams~$F(n)$ and independent
poles~$P(n)$.}
\end{table}
There are
\begin{equation}
P(n) = \frac{2^n-2}{2} - n = 2^{n-1} - n - 1
\end{equation}
independent internal momenta in a $n$-particle scattering
amplitude~\cite{ALPHA:1997}. This grows much slower than the
number
\begin{equation}
F(n) = (2n-5)!! = (2n-5)\cdot(2n-7)\cdot\ldots\cdot3\cdot1
\end{equation}
of tree Feynman diagrams in vanilla $\phi^3$ (see
table~\ref{tab:P(n),F(n)}). There are no known corresponding
expressions for theories with more than one particle type. However,
empirical evidence from numerical studies~\cite{ALPHA:1997,HELAC:2000}
as well as explicit counting results from O'Mega suggest
\begin{equation}
P^*(n) \propto 10^{n/2}
\end{equation}
while he factorial growth of the number of Feynman diagrams remains
unchecked, of course.
The number of independent momenta in an amplitude is a better measure
for the complexity of the amplitude than the number of Feynman
diagrams, since there can be substantial cancellations among the
latter. Therefore it should be possible to express the scattering
amplitude more compactly than by a sum over Feynman diagrams.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\section{Ancestors}
\label{sec:ancestors}
Some of the ideas that O'Mega is based on can be traced back to
HELAS~\cite{HELAS}. HELAS builts Feynman amplitudes by recursively
forming off-shell `wave functions' from joining external lines with
other external lines or off-shell `wave functions'.
The program Madgraph~\cite{MADGRAPH:1994} automatically generates
Feynman diagrams and writes a Fortran program corresponding to their
sum. The amplitudes are calculated by calls to HELAS~\cite{HELAS}.
Madgraph uses one straightforward optimization: no statement is
written more than once. Since each statement corresponds to a
collection of trees, this optimization is very effective for up to
four particles in the final state. However, since the amplitudes are
given as a sum of Feynman diagrams, this optimization can, by design,
\emph{not} remove the factorial growth and is substantially weaker
than the algorithms of~\cite{ALPHA:1997,HELAC:2000} and the algorithm
of O'Mega for more particles in the final state.
Then ALPHA~\cite{ALPHA:1997} (see also the slightly modified
variant~\cite{HELAC:2000}) provided a numerical algorithm for
calculating scattering amplitudes and it could be shown empirically,
that the calculational costs are rising with a power instead of
factorially.

\subsection{General purpose libraries}
Functions that are not specific to O'Mega and could be part of the
O'Caml standard library
\begin{modules}{}
\item[ThoList] (mostly) simple convenience functions for lists that
are missing from the standard library module \ocwupperid{List}
(section~\ref{sec:tholist}, p.~\pageref{sec:tholist})
\item[Product] effcient tensor products for lists and sets
(section~\ref{sec:product}, p.~\pageref{sec:product})
\item[Combinatorics] combinatorical formulae, sets of subsets, etc.
(section~\ref{sec:combinatorics}, p.~\pageref{sec:combinatorics})
\end{modules}
\subsection{O'Mega}
The non-trivial algorithms that constitute O'Mega:
\begin{modules}{}
\item[DAG] Directed Acyclical Graphs
(section~\ref{sec:DAG}, p.~\pageref{sec:DAG})
\item[Topology] unusual enumerations of unflavored tree diagrams
(section~\ref{sec:topology}, p.~\pageref{sec:topology})
\item[Momentum] finite sums of external momenta
(section~\ref{sec:momentum}, p.~\pageref{sec:momentum})
\item[Fusion] off shell wave functions
(section~\ref{sec:fusion}, p.~\pageref{sec:fusion})
\item[Omega] functor constructing an application from a model and a
target
(section~\ref{sec:omega}, p.~\pageref{sec:omega})
\end{modules}
\subsection{Abstract interfaces}
The domains and co-domains of functors
(section~\ref{sec:coupling}, p.~\pageref{sec:coupling})
\begin{modules}{}
\item[Coupling] all possible couplings (not comprensive yet)
\item[Model] physical models
\item[Target] target programming languages
\end{modules}
\subsection{Models}
(section~\ref{sec:models}, p.~\pageref{sec:models})
\begin{modules}{}
\item[Modellib_SM.QED] Quantum Electrodynamics
\item[Modellib_SM.QCD] Quantum Chromodynamics (not complete yet)
\item[Modellib_SM.SM] Minimal Standard Model (not complete yet)
\end{modules}
etc.
\subsection{Targets}
Any programming language that supports arithmetic and a textual
representation of programs can be targeted by O'Caml. The
implementations translate the abstract expressions derived by
\ocwupperid{Fusion} to expressions in the target
(section~\ref{sec:targets}, p.~\pageref{sec:targets}).
\begin{modules}{}
\item[Targets.Fortran] Fortran95 language implementation, calling
subroutines
\end{modules}
Other targets could come in the future: \texttt{C}, \texttt{C++},
O'Caml itself, symbolic manipulation languages, etc.
\subsection{Applications}
(section~\ref{sec:omega}, p.~\pageref{sec:omega})
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\section{The Big To Do Lists}
\label{sec:TODO}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\subsection{Required}
All features required for leading order physics applications are in place.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\subsection{Useful}
\begin{enumerate}
\item select allowed helicity combinations for massless fermions
\item Weyl-Van der Waerden spinors
\item speed up helicity sums by using discrete symmetries
\item general triple and quartic vector couplings
\item diagnostics: count corresponding Feynman diagrams
more efficiently for more than ten external lines
\item recognize potential cascade decays ($\tau$, $b$, etc.)
\begin{itemize}
\item warn the user to add additional
\item kill fusions (at runtime), that contribute to a cascade
\end{itemize}
\item complete standard model in $R_\xi$-gauge
\item groves (the simple method of cloned generations works)
\end{enumerate}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\subsection{Future Features}
\begin{enumerate}
\item investigate if unpolarized squared matrix elements can be
calculated faster as traces of densitiy matrices. Unfortunately,
the answer apears to be \emph{no} for fermions and \emph{up to a
constant factor} for massive vectors. Since the number of fusions
in the amplitude grows like~$10^{n/2}$, the number of fusions in
the squared matrix element grows like~$10^n$. On the other hand,
there are $2^{\#\text{fermions}+\#\text{massless vectors}}
\cdot3^{\#\text{massive vectors}}$ terms in the helicity sum, which
grows \emph{slower} than~$10^{n/2}$. The constant factor is
probably also not favorable.
However, there will certainly be asymptotic gains for sums over
gauge (and other) multiplets, like color sums.
\item compile Feynman rules from Lagrangians
\item evaluate amplitues in O'Caml by compiling it to three address
code for a virtual machine
\begin{flushleft}
\ocwkw{type}~$\ocwlowerid{mem}~=~\ocwlowerid{scalar}~$\ocwbt{array}~$%
\times{}~\ocwlowerid{spinor}~$\ocwbt{array}~$%
\times{}~\ocwlowerid{spinor}~$\ocwbt{array}~$%
\times{}~\ocwlowerid{vector}~$\ocwbt{array}\\
\ocwkw{type}~$\ocwlowerid{instr}~=$\\
\qquad|~$\ocwupperid{VSS}~$\ocwkw{of}~\ocwbt{int}~$%
\times{}~$\ocwbt{int}~$\times{}~$\ocwbt{int}\\
\qquad|~$\ocwupperid{SVS}~$\ocwkw{of}~\ocwbt{int}~$%
\times{}~$\ocwbt{int}~$\times{}~$\ocwbt{int}\\
\qquad|~$\ocwupperid{AVA}~$\ocwkw{of}~\ocwbt{int}~$%
\times{}~$\ocwbt{int}~$\times{}~$\ocwbt{int}\\
\qquad\ldots
\end{flushleft}
this could be as fast as~\cite{ALPHA:1997} or~\cite{HELAC:2000}.
\item a virtual machine will be useful for for other target as
well, because native code appears to become to large for most
compilers for more than ten external particles. Bytecode might
even be faster due to improved cache locality.
\item use the virtual machine in O'Giga
\end{enumerate}

\chapter{Trees}
\label{sec:tree}
From~\cite{Ohl:bocages}:
Trees with one root admit a straightforward recursive definition
\begin{equation}
\label{eq:trees}
T(N,L) = L \cup N\times T(N,L)\times T(N,L)
\end{equation}
that is very well adapted to mathematical reasoning. Such
recursive definitions are useful because they
allow us to prove properties of elements by induction
\begin{multline}
\label{eq:tree-induction}
\forall l\in L: p(l) \land
(\forall n\in N: \forall t_1,t_2\in T(N,L): p(t_1) \land p(t_2)
\Rightarrow p(n\times t_1\times t_2)) \\
\Longrightarrow \forall t\in T(N,L): p(t)
\end{multline}
i.\,e.~establishing a property for all leaves and showing that a node
automatically satisfies the property if it is true for all children
proves the property for \emph{all} trees. This induction is of course
modelled after standard mathematical induction
\begin{equation}
p(1) \land (\forall n\in \mathbf{N}: p(n) \Rightarrow p(n+1))
\Longrightarrow \forall n\in \mathbf{N}: p(n)
\end{equation}
The recursive definition~(\ref{eq:trees}) is mirrored by the two tree
construction functions\footnote{To make the introduction more
accessible to non-experts, I avoid the `curried' notation for
functions with multiple arguments and use tuples instead. The actual
implementation takes advantage of curried functions, however. Experts
can read $\alpha\to\beta\to\gamma$ for $\alpha\times\beta\to\gamma$.}
\begin{subequations}
\begin{align}
\ocwlowerid{leaf}:\;& \nu\times\lambda \to(\nu,\lambda) T \\
\ocwlowerid{node}:\;& \nu\times(\nu,\lambda)T \times(\nu,\lambda)T
\to(\nu,\lambda)T
\end{align}
\end{subequations}
Renaming leaves and nodes leaves the structure of the tree invariant.
Therefore, morphisms~$L\to L'$ and~$N\to N'$ of the sets of leaves
and nodes induce natural homomorphisms~$T(N,L)\to T(N',L')$ of trees
\begin{equation}
\ocwlowerid{map}:\; (\nu\to\nu')\times(\lambda\to\lambda')
\times(\nu,\lambda)T \to(\nu',\lambda') T
\end{equation}
The homomorphisms constructed by \ocwlowerid{map} are trivial, but
ubiquitous. More interesting are the morphisms
\begin{equation}
\begin{aligned}
\ocwlowerid{fold}:\;& (\nu\times\lambda\to\alpha)
\times(\nu\times\alpha\times\alpha\to\alpha)
\times(\nu,\lambda)T \to\alpha \\
& (f_1,f_2,l\in L) \mapsto f_1(l) \\
& (f_1,f_2,(n,t_1,t_2)) \mapsto
f_2(n,\ocwlowerid{fold}(f_1,f_2,t_1),
\ocwlowerid{fold}(f_1,f_2,t_2))
\end{aligned}
\end{equation}
and
\begin{equation}
\begin{aligned}
\ocwlowerid{fan}:\;& (\nu\times\lambda\to\{\alpha\})
\times(\nu\times\alpha\times\alpha\to\{\alpha\})
\times(\nu,\lambda)T \to\{\alpha\} \\
& (f_1,f_2,l\in L) \mapsto f_1(l) \\
& (f_1,f_2,(n,t_1,t_2)) \mapsto
f_2(n, \ocwlowerid{fold}(f_1,f_2,t_1)
\otimes\ocwlowerid{fold}(f_1,f_2,t_2))
\end{aligned}
\end{equation}
where the tensor product notation means that~$f_2$ is applied to all
combinations of list members in the argument:
\begin{equation}
\phi(\{x\}\otimes \{y\})
= \left\{ \phi(x,y) | x\in\{x\} \land y\in\{y\} \right\}
\end{equation}
But note that due to the recursive nature of trees, \ocwlowerid{fan} is
\emph{not} a morphism from $T(N,L)$ to $T(N\otimes N,L)$.\par
If we identify singleton sets with their members, \ocwlowerid{fold} could be
viewed as a special case of \ocwlowerid{fan}, but that is probably more
confusing than helpful. Also, using the special
case~$\alpha=(\nu',\lambda')T$, the homomorphism \ocwlowerid{map} can be
expressed in terms of \ocwlowerid{fold} and the constructors
\begin{equation}
\begin{aligned}
\ocwlowerid{map}:\;& (\nu\to\nu')\times(\lambda\to\lambda')
\times(\nu,\lambda)T \to(\nu',\lambda')T \\
&(f,g,t) \mapsto
\ocwlowerid{fold} (\ocwlowerid{leaf}\circ (f\times g),
\ocwlowerid{node}\circ (f\times\ocwlowerid{id}
\times\ocwlowerid{id}), t)
\end{aligned}
\end{equation}
\ocwlowerid{fold} is much more versatile than \ocwlowerid{map}, because it can be used
with constructors for other tree representations to translate among
different representations. The target type can also be a mathematical
expression. This is used extensively below for evaluating Feynman
diagrams.\par
Using \ocwlowerid{fan} with~$\alpha=(\nu',\lambda')T$ can be used to construct
a multitude of homomorphic trees. In fact, below it will be used
extensively to construct all Feynman
diagrams~$\{(\nu,\{p_1,\ldots,p_n\})T\}$ of a given
topology~$t\in (\emptyset,\{1,\ldots,n\})T$.
\begin{dubious}
The physicist in me guesses that there is another morphism of trees
that is related to \ocwlowerid{fan} like a Lie-algebra is related to the
it's Lie-group. I have not been able to pin it down, but I guess that it
is a generalization of \ocwlowerid{grow} below.

%%%
%%% \section{Architecture}
%%% In \texttt{lablgtk}, O'Caml objects are typically constructed in
%%% parallel to constructors for \texttt{GTK+} widgets. The objects
%%% provide inheritance and all that, while the constructors implement the
%%% semantics.
%%%
%%% \subsection{Inheritance vs.~Aggregation}
%%% We have two mechanisms for creating new widgets: inheritance and
%%% aggregation. Inheritance makes it easy to extend a given widget with
%%% new methods or to combine orthogonal widgets (\emph{multiple
%%% inheritance}). Aggregation is more suitable for combining
%%% non-orthogonal widgets (e.\,g.~multiple instances of the same widget).
%%%
%%% The problem with inheritance in \texttt{lablgtk} is, that it is a
%%% \emph{bad} idea to implement the semantics in the objects. In a
%%% multi-level inheritance hierarchy, O'Caml can evaluate class functions
%%% more than once. Since functions accessing \texttt{GTK+} change the
%%% state of \texttt{GTK+}, we could accidentally violate invariants.
%%% Therefore inheritance forces us to use the two-tiered approach of
%%% \texttt{lablgtk} ourselves. It is not really complicated, but tedious
%%% and it appears to be a good idea to use aggregation whenever in doubt.
%%%
%%% Nevertheless, there are examples (like
%%% \ocwupperid{ThoGButton.mutable\_button} below, where just one new
%%% method is added), that cry out for inheritance for the benefit of the
%%% application developer.
