Closed moosebuild closed 2 days ago

Description of the Issue

When solving a problem using the implicit non segregated solver (monolithic) the resulting solution is invariant to β. Screen_Shot_2022-09-14_at_12.43.55_PM

Information for reproducing the error

Run psbt.iwithpower_profile.txt in the same folder. Change β and notice how this doesn't affect the solution while it does affect it in the case of the explicit solver. (see attached graph)

PSBT-CT

Identified impact

This will allow us to toggle the β factor so that the implicit solver will match benchmark results.
