چکیده

Genetic Vehicle Representation (GVR) is a new two-level representational scheme designed to encode all the information required by potential solutions for the vehicle routing problem. In a previous paper we described a set of experiments performed with several instances from the Capacitated Vehicle Routing Problem (CVRP). In this preliminary investigation, GVR proved to be both effective and robust. In this work we extend the application of this new genetic representation to the vehicle routing problem with time windows, a variant that adds additional time constraints to the original definition. We present the results of a comprehensive set of tests that show that GVR is also efficient with this alternative, allowing the evolutionary computation algorithm to reach optimal solutions for some well know benchmarks.

Applying GVR to Molecular Dynamics: Enabling Resilience for Scientific Computations

In future exascale systems [1]-[4], resilience is a major concern. Molecular dynamics codes are an important computational method in a wide variety of areas of biology, chemistry, and physics. We applied the GVR (global view resilience) library to the ddcMD (domain decomposition molecular dynamics) code, both to explore application resilience challenges and evaluate the potential for GVR to bro...
