Second, the conversion to a single-objective optimization problem involves additional constraints. Third, since most real-world goal programming problems involve nonlinear criterion functions, the ...

A pattern separation problem is basically a problem of obtaining a criterion for distinguishing between the elements of two disjoint sets of patterns. The patterns are usually represented by points in ...

Incorporating waiting and service times at the facilities while determining their locations and capacities simultaneously results in a nonlinear mixed-integer programming formulation that can be ...

To solve the problem, the authors use a partial outer convexification approach, which involves two stages: the solution of a (smoothed) nonlinear programming problem with dynamic constraints and a ...

Nonlinear programs can be input into the procedure in various ways. The objective, constraint, and derivative fucntions are specified using the programming statements of PROC NLP.
