Deprecated:
The LexiographicSearch for bandwidth optimization is not in use. Can it be removed?

Here is the call graph for this function:

 integer function bandwidthoptimize::optimizebandwidth ( type(listmatrix_t), dimension(:) ListMatrix, integer, dimension(:) Perm, integer, dimension(:) InvInitialReorder, integer LocalNodes, logical Optimize, logical UseOptimized, character(len=*) Equation )

Subroutine for reordering variables for bandwidth and/or gaussian elimination fillin optimization. Also computes node to element connections (which implies node to node connections, and thus the global matrix structure).
