Optimización sustitutiva
Solucionador de optimización sustituto para funciones objetivo costosas, con límites y restricciones de números enteros opcionales
Utilice la optimización sustituta para funciones objetivas costosas (que consumen mucho tiempo). El solucionador requiere límites finitos en todas las variables, permite restricciones de desigualdad no lineal y acepta restricciones de números enteros en variables seleccionadas. El solucionador puede guardar opcionalmente su estado después de cada evaluación de función, lo que permite la recuperación de detencións prematuras.
