Pontryagin's Principle For Local Solutions of Control Problems with Mixed Control-State Constraints
This paper deals with optimal control problems of semilinear parabolic equations with pointwise state constraints and coupled integral state-control constraints. We obtain necessar...

Sampling the Repairs of Functional Dependency Violations under Hard Constraints
Violations of functional dependencies (FDs) are common in practice, often arising in the context of data integration or Web data extraction. Resolving these violations is known to...

Rounding to an Integral Program
We present a general framework for approximating several NP-hard problems that have two underlying properties in common. First, the problems we consider can be formulated as intege...
