Abstract : This dissertation considers two combinatorial problems arising in largescale, sparse optimizaton. The first is the problem of approximating the Hessian matrix of a smooth, nonlinear function by finite differencing, where the object is to minimize the required number of gradient evaluations. The second is to find as sparse a representation as possible of a given set of linear constraints.
