Directed Feedback Vertex Set is Fixed-Parameter Tractable
Igor Razgon,Barry O'Sullivan +1 more
TL;DR: In this paper, the fixed-parameter tractability of the DFTV problem was shown to be tractable in O(8^k!*poly(n)) time.
Book ChapterDOI
Case-Based Reasoning for Autonomous Constraint Solving
TL;DR: Faced with a new problem, humans recall their experiences in solving similar problems in the past, and they modify the past solutions to fit the circumstances of the new problem.

Guiding Search using Constraint-level Advice
TL;DR: This paper shows that constraints can also be used to guide the search process by actively proposing the next choice point to be branched on, and shows that search effort can be reduced significantly.
Combining Branch&Bound and SBDD to solve Soft CSPs
TL;DR: Soft-SBDD, a generalization of Symmetry Breaking via Dominance Detection, is presented, and theoretical results demonstrating that symmetry breaking in soft constraint satisfaction problems improves the efficiency of search are presented.
