Performance and Gap Settings of Lindo Global Solver

Support
1

Hi,
I encountered the problem of long solving time when using the Lindo global solver, possibly due to the presence of a large number of 0-1 and integer variables, as well as cumulative nested constraints on variables.
Based on this issue, I have tried to set up the solution core and adjust the solution mode, but still have not achieved good results. Do you have a good way to improve the solution speed or adjust the gap value (currently, the way to set the gap is not found in the help document).

Thanks in advance

The AMPL interface to LINDO Global was written by LINDO Systems, the developers of the LINDO family of products. We have written to them to ask whether their interface provides access to the many LINDO Global options, and I’ll post here anything that we learn.
