“…However, FM elimination is not a valid proof system for a system of integer inequalities; [55] provides examples where FM is not sound. Proofs in integer arithmetic usually use cutting plane theory [9]. The resolution technique for clausal formulas has a number of variants including tree-like resolution, dag-like resolution, read-once resolution, linear resolution, and so on [13,42].…”

“…Some of the concepts that are most relevant to the work presented here are: decomposition approaches (e.g. Benders [3]) that solve parts of the problem with different techniques [10,14,19,21,24,33]; allowing different models/solvers to exchange information [32]; using linear programming to reduce the domains of variables or to fix them to certain values [4,11,32]; automatic reformulation of global constraints as systems of linear inequalities [30]; continuous relaxations of global constraints and disjunctions of linear systems [1,14,18,22,28,36,37,38]; understanding the generation of cutting planes as a form of logical inference [6,7]; strengthening the problem formulation by embedding the generation of valid cutting planes into CP constraints [12]; maintaining the continuous relaxation of a constraint updated when the domains of its variables change [29]; and using global constraints as a key component in the intersection of CP and OR [27].…”

“…Note that under the assumption that NP = co-NP, 3SAT formulas cannot have polynomial sized refutations. Exponential lower bounds for propositional formulas using cutting plane proof systems were first shown in Pudlák [1997]; applications of cutting plane theory to propositional proof systems are also discussed in Bockmayr and Eisnbrand [2000]. Exhaustive surveys of Propositional proof complexity can be found in Beame and Pitassi [1998] and Urquhart [1995].…”
