On optimal strong Mal'cev conditions for congruence meet-semidistributivity in a locally finite variety

Jelena Jovanović

In this paper we examine four--element and five-element digraphs for existence of certain polymorphisms that imply congruence meet--semidistribu\-tivity in a locally finite variety. The results presented here occurred as an integral part of my research for optimal strong Mal'cev conditions describing the property mentioned. Most of the programming needed to obtain these results was done in C programming language, but for some results we also used the model builder Paradox. The source codes and Paradox inputs will be presented here as well.
