skip IDIC if the generation problem returns infeasible solution - follow up #139

Open yuxies opened 5 months ago

This PR fixed a bug in a previous change #131 that skipped the generation of an improving direction intersection cut when the generation problem returned an all-zero solution.

The new line determines the all-zero solution using the defined tolerance instead of zero.
