When Magma is not detected, one can specify its location by passing-DHIOP_MAGMA_DIR=/path/to/magma/dirto cmake. For custom CUDA Toolkit installations, the locations to the (missing/not found) CUDA libraries can be specified to cmake via-DNAME=/path/cuda/directory/lib, whereNAMEcan be an...
In an initial test, we found IPOPT produces solutions that are not compatible with the ReEDS sequential-solve algorithmic structure [11]. For example, after solving one model year, IPOPT would include nonzero values for variables not considered in the model. These nonzero values would create ...
SOLVER selects the solver to use in an attempt to find a solution. There are free solvers: 1: APOPT, 2: BPOPT, 3: IPOPT distributed with the public version of the software. There are additional solvers that are not included with the public version and require a commercial license. IPOPT...
not always help. For example, the presolving algorithms used in some solvers may cause the advanced basis to be ignored. Further, solvers may perform poorly when the advanced basis provided is worse than what the solver would otherwise have constructed with its own heuristics. Finally, not all...
meanwhile, I have found a way to split my MINLP into MILP and NLP; the former is working very well with CBC in Matlab, while the latter does work, but performance is not that good and results depend very much on good initial guesses, even with a global optimizer. I suppose it is bec...
