The research of Professor André Amaral involves:
Often, in these application areas one has to solve a Combinatorial Optimization Problem (one whose set of feasible solutions can be considered to be discrete). When this is the case, he has sometimes resorted to Polyhedral combinatorics (study of the facets of a polytope, whose vertices correspond to the solutions of a combinatorial optimization problem.). The realworld problems considered in his research are generally intractable, which means that the computational effort required to solve them increases exponentially with their size. Professor Amaral has been working on the development of novel methods to effectively compute proven optimal solutions for mediumsized instances of ever larger sizes. For largescale sized problems, he has been developing heuristic methods that can find good solutions in reasonable time. It is observed that Prof. Amaral's research is at the interface of Applied Mathematics, Theoretical Computer Science, Operations Research and Production Engineering.
