The Complexity of Polynomial-Time Approximation
In 1996, Khanna and Motwani [KM96] proposed three logic-based optimization problems constrained by planar structure, and offered the hypothesis that these putatively fundamental ...

Data exchange: computing cores in polynomial time
Data exchange deals with inserting data from one database into another database having a different schema. We study and solve a central computational problem of data exchange, nam...

Satisfiability Allows No Nontrivial Sparsification Unless The Polynomial-Time Hierarchy Collapses
Consider the following two-player communication process to decide a language L: The first player holds the entire input x but is polynomially bounded; the second player is computa...

Efficient Approximation Algorithms for the Subset-Sums Equality Problem
We investigate the problem of finding two nonempty disjoint subsets of a set of n positive integers, with the objective that the sums of the numbers in the two subsets be as close ...

Extensions and restrictions of Wythoff's game preserving its p positions
We consider extensions and restrictions of Wythoff’s game having exactly the same set of P positions as the original game. No strict subset of rules give the same set of P posit...
