    Hi Isabella,

    Gurobi uses many different heuristics to find feasible solution points. Most of them are well known and can be found in the literature, e.g., feasibility pump or neighborhood searches. You can see whether a feasible point has been found by some heuristic if there is an "H" written as the first character of a B&B line. If there is an asterisk " * ", then a feasible point has been found by branching, see MIP Logging. It is not possible to determine which heuristic found the given feasible solution.

    To learn more, I strongly recommend having a look and our Webinars and Events and Books and Blogs sections.

    Best regards,
    Jaromił
