Solver Settings Explanation

The HOPE model can use multiple solvers to solve optimization problems. The recommended default solver is HiGHS (highs), which is open-source, fast, and requires no extra installation. The solver parameters are saved in settings files named <solver>_settings.yml (e.g., highs_settings.yml, cbc_settings.yml, clp_settings.yml, cplex_settings.yml, gurobi_settings.yml, scip_settings.yml). In general, users do not need to modify these files. Each solver may have its own different settings parameters; if one wants to modify these parameters, it would be better to check the corresponding solver's documentation.
