Abstract
Efficient determination of large sparse Hessian matrices leads to solving many optimization problems. Exploiting sparsity and symmetry of the Hessian matrix can reduce the number of function evaluations required to determine the matrix. This sparse matrix determination problem can be posed as a graph coloring problem. Graph formulation of the problem using an appropriate model can lead to a better exposition of the matrix compression heuristics.
