Computing optimal locally constrained steps
WebMay 1, 2016 · Take the SPOTRF example, spotrfx.f, from the MKL distribution, and the matching data file, spotrfx.d. Change the last two diagonal elements to 0.56 and 0.18. You will find that Cholesky factorization fails and the matrix A gets overwritten, even though the leading 3 X 3 submatrix is definite. The cure, however, is simple, as you probably know ... WebWe study an approach for minimizing a convex quadratic function subject to two quadratic constraints. This problem stems from computing a trust-region step for an SQP algorithm proposed by Celis, Dennis and Tapia (1985) for equality constrained optimization. Our approach is to reformulate the problem into a univariate nonlinear equationφ(μ)=0 where …
