Installing in Windows seems a lot of pains if we follow the instruction from the [source](https://www.coin-or.org/download/source/Couenne/). Fortunately, there is a pre-compiled binary for Windows available at [coin-or website](https://www.coin-or.org/download/binary/Couenne/). Sadly, latest...
Hello, When investigating a problem with my tool (to figure out why Couenne was marking it as unfeasible when it was supposed to have a solution), I encountered a peculiar...
Hello I will appreciate if someone can help with the meaning of this code: ERROR: Solver (asl) returned non-zero return code (3221226505) best regards MCoimbra
