Exact l penalty function for nonsmooth multiobjective interval-valued problems
Our objective in this article is to explore the idea of an unconstrained problem using the exact l penalty function for the nonsmooth multiobjective interval-valued problem (MIVP) having inequality and equality constraints. First of all, we figure out the KKT-type optimality conditions for the problem (MIVP). Next, we establish the equivalence between the set of weak LU-efficient solutions to the problem (MIVP) and the penalized problem (MIVP) with the exact l penalty function. The utility of...
