Description: The optimqr program will read a description of the sparsity pattern of some system matrix for system of linear equations. It will then apply heuristic branch and bound search to find a near-optimal ordering of the rows and columns of the system matrix. The ordering is written to disk. The codegen.pl program can then read the system ordering, and create a solver written in Fortran 77, that will solve the system using sparse QR factorization (using Givens rotations).
A Software-package to create near-optimal solvers for sparse systems of linear equations OptimQR is a package consisting of several programs: program will read a description of the sparsity pattern of some system matrix for system of linear equations. It will then apply heuristic branch&bound search to find a near-optimal ordering of the rows and columns of the system matrix. The ordering is written to disk.
