摘要:We prove exponential separations between the sizes of particular refutations in negative, respectively linear, resolution and general resolution. Only a superpolynomial separation between negative and general resolution was previously known. Our examples show that there is no strong relationship between the size and width of refutations in negative and linear resolution.
