Taiwanese Journal of Mathematics, Vol. 27, No. 2 (April 2023), pp. 221-236 (16 pages) We prove a new case of mixed discrete joint universality theorem on approximation of certain target couple of ...

In this paper we develop interactive approaches for the discrete alternative multiple criteria decision making problem. We develop an algorithm that finds the most preferred alternative of a decision ...

Ordinary differential equations (ODEs) and difference equations serve as complementary tools in the mathematical modelling of processes evolving in continuous and discrete time respectively. Together ...
