Abstract. In this paper, some interval valued programming problems are discussed. The solution concepts are adopted fromWu [7] and Chalco-Cano et al. [34]. By considering generalized Hukuhara ...

This paper develops a new algorithm for solving the general nonlinear programming problem that melds the flexible simplex search of Nelder and Mead with various additional rules to take care of ...

To make things worse, the problems are nonlinear and have mixed-integer decisions," explains Potschka. "Most approaches so far either drop the nonlinearity in favor of a relatively coarse piecewise ...
