Lasserre Gaps and Asymmetry of Random Graphs Ryan ODonnell CMU John Wright CMU Chenggang Wu Tsinghua Yuan Zhou CMU Hardness of Robust Graph Isomorphism Lasserre Gaps. Sometimes, two graphs have exactly the same form, in the sense that there is a one-to-one correspondence between their vertex sets that preserves edges. In such a case, we say that the two graphs are . Tali Kaufman. Joint work with Irit Dinur. Codes as CSPs . A constraint satisfaction problem (CSP) is a sequence of constraints over variables:. f. 1 .
