A SAT solver method that learns extra constraints from conflicts.
CDCL is like a kid in a corn maze with a marker. Every dead end gets a big NOPE sign, so whole paths get skipped.
It powers SAT solvers. It helps check designs and plan steps by turning dead ends into shortcuts.
DPLL
CDCL adds conflict learning to DPLL backtracking search.
CSP
SAT is a Boolean CSP, and CDCL is built to solve it.
Resolution
A new clause learned by CDCL can act like a Resolution step.
ATP
Modern ATP often hands SAT solving to CDCL.
