Added user propagator example (#5625)
* Added user propagator example

* User propagator example code refactoring
(+ removed unused parameter warning)

* Moved user-propagator example to its own directory
2021-11-02 15:03:02 -07:00
Nikolaj Bjorner 87d4ce2659 working on #5614
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.

FYI @levnach

fix grouping for latest doxygen (#5626)
Since doxygen 1.8.16, opening and closing a group must not be done as
C comment but as doxygen command. In other words, not one but two
asterisk characters are required so that doxygen finds a group.

* feat(api/ml): use custom block hints to guide the GC

this forces the GC to collect garbage when a few _large_ objects
(solver, etc.) are dead. The current code would let arbitrarily many
such objects die and not trigger a GC (which would have to come from
OCaml code instead)
