Research

Optimization (i.e. determining an optimal choice when restricted by constraints); mathematical programming; operations research; modelling; linear and non-linear programming; heuristics; infeasibility analysis; developing algorithms to debug optimization models and to speed optimization solutions.

Application

Optimization is widely used in engineering and business. An example is optimal scheduling for airlines in delivering passengers at minimum cost against constraints of aircraft maintenance and crew scheduling. Recent application has been in improved task allocation in cloud computing.
