In this paper a new hybrid glowworm swarm algorithm (SAGSO) for solving structural optimization problems is presented. The structure proposed to be optimized here is a simply-supported concrete I-beam ...

This is guaranteed to be a valid cut of the LP relaxation of an integer programming problem. We use the Python implementation of CPLEX, to get the final tableau. We ...

Uncertainties are widespread in the optimization of process systems, such as uncertainties in process technologies, prices, and customer demands. In this paper, we review the basic concepts and recent ...

The Dynamic Vehicle Routing Problem with Stochastic Requests (DVRPSR) is a prototypical problem in transportation logistics. The DVRPSR calls for an initial route plan and an online scheduling policy ...
