We show that Cutting Planes (CP) proofs are hard to find: Given an unsatisfiable formulaF, It is -hard to find a CP refutation ofFin time polynomial in the length of the shortest such refutation; and unless Gap-Hitting-Set admits a nontrivial algorithm, one cannot find atree-likeCP refutation ofFin time polynomial in the length of the shortest such refutation.The first result extends the recent breakthrough of Atserias and M'uller (FOCS 2019) that established an analogous result for Resolution. Our proofs rely on two new lifting theorems: (1) Dag-like lifting for gadgets withmany output bits. (2) Tree-like lifting that simulates anr-round protocol with gadgets of query complexityO(r).
