Algorithm and software are proposed for computing behavior, for establishing equivalence and redundancy of states and for solving reduction and minimization problems. Computational complexity of the algorithm is discussed. Testing examples are supplied. The results are valid for finite max–min, min–max and max–product fuzzy machines.

Algebraic-logical approach and procedures for inverse problem resolution are proposed. They provide algorithm for solving fuzzy linear system of equations in Godel algebra, product (Goguen) algebra and Lukasiewicz algebra: when the system is consistent, its complete solution set is calculated. In case of inconsistency, the equations that can
