Better error when no solution found #150

Closed marcosfelt closed 1 year ago

marcosfelt commented 1 year ago

Currently, when the solver doesn't find a solution, it raises a generic exception. Using a generic exception makes it difficult to specifically catch failed solutions and do custom error handling.

Would you accept a PR that creates a custom error for failed solutions?

Try setting debug=0 to allow the code to proceed without the exception with m.solve(debug=0). The status is reported by m.options.APPSTATUS or m.options.APPINFO for more specific error information.
