We address the tensions between the established curricula recommendations from one side, and the cultural, axiological, po...

Programação matemática e imersões métricas para aproximações em problemas de corte

In this work, we present a theoretical study about NP-hard optimization problems of cuts in graphs and the state of the art in approximation algorithms that use techniques of mathematical programming and of metric spaces. Three problems of cuts in graphs were modeled by integer mathematical programs and they are relaxed to admit solutions with continuous values. The solution of these programs d...
