HeurBeforeLPGPUMethod Property

Enables a GPU-accelerated heuristic of the specified type. If enabled, this heuristic is called as a BEFORELP heuristic for multiple rounds. The control value XPRS_HEURBEFORELPGPUMETHOD_FEASPUMP enables a GPU accelerated version of feasibility pump. In each round, the LP relaxation is approximately solved using the Primal Dual Hybrid Gradient algorithm on the GPU, The fractional solution is then rounded, and a heuristic is called to minimize the remaining violations. The effort spent on this final polishing step can be controlled by the user.
