TestEquations: A repository from Mazdaywik

This repository presents results of the specialization of the word equations interpreter WECount by equations given as a benchmark for the solver Woorpje, download here. The description of the equations in the track is given here.

The interpreter source code is weqs_int_bench_task.ref, where the input equation is to be replaced by the one to be solved.

The equations are encoded as follows.

Variables are encoded as As, Bs, ...., Xs.
Letters (constant symbols) are encoded as a, b,...,x.

Residual programs that correspond to equations with no solutions contain the single rule:

$ENTRY Go {
  (e.101) = False;
}

The other residual programs model graphs of all solutions of the corresponding equations.

The paths in graphs contain the following labels:

('Xs -> empty') — variable Xs has the value the empty string;
('Xs -> Ys Xs') — variable Xs has the prefix Ys;
('Xs -> a Xs') — variable Xs starts by the letter a.

Say, given the path ('Xs -> a Xs')('Xs -> Ys Xs')('Xs -> empty') it models the solution Xs = a Ys.

The overall results of the verification are given in the table below. If 'Has Solutions' is '!' then the equation is solvable but the timeout occurred.

Solutions type is 0 if the solutions are unions of patterns (the solution graph is a tree); is 'regular' if the solution graph contains loops, but these loops generate regular expressions; and is 'non-regular' if the solution graph contains some other loops.

All the equations are classified in their reduced form. E.g. the equation As Bs = As As counts as acyclic, because the two occurrences of As are reduced.

Acyclic equations which are not quadratic have the sides with the empty intersection of the variables and are linear with respect to one side.

For example, the equation As As As = Bs a Cs is acyclic, however it is not quadratic.
