Description/Abstract

Combinatorial optimisation usually involves many iterations, which makes such approaches computationally expensive, especially when dealing with complex finite element models. This paper proposes to use a surrogate model that can bring down the computational expense of sequential combinatorial finite element problems. The idea of using such model is illustrated on a welding example.
