there are some different sources for the performance regression illustrated by the example. The mitigations will be enabled separately:
- m_bv_to_propagate is too expensive
- lp_bound_propagator misses equalities in two different ways:
- it resets row checks after backtracking even though they could still propagate
- it misses equalities for fixed rows when the fixed constant value does not correspond to a fixed variable.
