“…Hanson [19] discussed the relationship between optimization problems and variational problems. Later, several researchers have shown their interest to solve the variational control problems (see, for example, [2,3,4,10,12,14,22,25,27,34,36] and others). Craven [17], remarkably established KT-type necessary conditions for multiobjective variational problems under pseudo and quasi convexity assumptions.…”
