In this project we intend to design GPU-based algorithms to solve unconstrained binary quadratic programming problems (UQP). These problems consist of minimize or maximize a quadratic function over binary numbers. Many combinatorial optimization problems can be put in the UQP form, for example k-coloring graph, maximum clique, maximum independent set, etc. In particular, we intend to solve cutting and packing problems. A relevant problem in this field is the manufacturer's pallet loading problem (MPL) which consists of packing identical items (for example boxes) into larger objects (pallets). The MPL can be viewed as a maximum independent set and this can be transformed to the UQP form. (AU)
