PPT-Circuit Lower Bounds A combinatorial approach to P

vs NP Shachar Lovett Computation Input Memory Program Code Program code is constant Input has variable length n Run time memory grow with input length Efficient algorithms run time memory . Our result is modular 1 We describe a carefullychosen dynamic version of set disjointness the multiphase problem and conjecture that it requires 84861 time per operation All our lower bounds follow by easy reduction 2 We reduce 3SUM to the multipha The heart of this technique is a complex ity measure for multivariate polynomials based on the linear span of their partial derivatives We use the technique to obtain new lower bounds for computing sym metric polynomials which hold over 64257elds of Indeed developing bounds on the per formance of procedures can give complementary insights By exhibiting fundamental limits of performance perhaps over restricted classes of estimators it is possible to guarantee that an a lgorithm we have developed fanin.
