Intersection Classes in TFNP and Proof Complexity

Information Technology Convergence and Services
A recent breakthrough in the theory of total NP search problems (TFNP) by Fearnley, Goldberg, Hollender, and Savani has shown that CLS = PLS ∩ PPAD , or, in other words, the class of problems reducible to gradient descent are exactly those problems in ...

Total NP Search Problems with Abundant Solutions

Information Technology Convergence and Services
We define a new complexity class TFAP to capture TFNP problems that possess abundant solutions for each input. We identify several problems across diverse fields that belong to TFAP , including WeakPigeon (finding a collision in a mapping from [2 n ...
