The termination property of the CDCL algorithm is not that obvious (at least to me). It is hypothetical that some paths may be repeatedly reached, since the backjump mechanism does not systematically ...

Purists go 1992. Newer or younger fans go 2018. Psychopaths go 2022. There are arguments to be made for several Rumbles to claim vaunted greatest-of-all-time status, but there's none with the range of ...

Abstract: We present a general algorithm which gives a uniform view of several state-of-the-art systematic backtracking search algorithms for solving both binary and nonbinary CSP instances. More ...

Previously, the solver represented an unknown package with an empty PChoice node, because an unknown package is like a package with no versions. Now that --reject-unconstrained-dependencies also needs ...
