Abstract. The results of tests of formula simplification tools are presented in the first part of the paper. In the second part, the algorithm for constructing canonical forms of linear semi-algebraic formulas is described. The main result of the study is the definition of the canonical form of linear semi-algebraic formula, which has the property of uniqueness and other useful properties. The algorithm of its construction is described.
Keywords: systems of linear inequalities, algebraic programming, software verification, canonical forms, linear semialgebraic formulas.
