A friendly language for propositional logic and more
Beyond the Boolean connectives of propositional logic, the input language of TouIST allows sets, conjunctions and disjunctions parametrized by sets, abbreviations… You can express complex propositional formulas as
which is, in TouIST:
bigand $i in [left,right]: p($i) end
We can conveniently express and solve problems such the sudoku (see the example).
The team behind TouIST consists of Frédéric Maris (Associate Professor), Olivier Gasquet (Full Professor), Dominique Longin (Research Scientist) and Maël Valais (PhD student) at the Institut de Recherche en Informatique de Toulouse (IRIT). It is a “second” or “new” version of a previous program, SAToulouse. TouIST is now actively developed in context of Maël Valais' PhD thesis.
