چکیده
A graph class is hereditary if it closed under vertex deletion. We give examples of NP-hard, PSPACE-complete and NEXPTIME-complete problems that become constant-time solvable for every not equal to the all graphs.

Hard Knapsack Problems That Are Easy for Local Search
Chvv atal (1980) describes a class of zero-one knapsack problems provably diicult for branch and bound and dynamic programming algorithms. Chung et al. (1988) identiies a class of integer knapsack problems hard for branch and bound algorithms. We show that for both classes of problems local search provides optimal solutions quickly.
متن کاملEasy Problems are Sometimes Hard
We present a detailed experimental investigation of the easy-hard-easy phase transition for randomly generated instances of satisfiability problems. Problems in the hard part of the phase transition have been extensively used for benchmarking satisfiability algorithms. This study demonstrates that problem classes and regions of the phase transition previously thought to be easy can sometimes be...
متن کاملHard and Easy Distributions of SAT Problems
We report results from large-scale experiments in satis-ability testing. As has been observed by others, testing the satissability of random formulas often appears surprisingly easy. Here we show that by using the right distribution of instances, and appropriate parameter values, it is possible to generate random formulas that are hard, that is, for which satissability testing is quite diicult....
متن کاملSome Very Easy Knapsack / Partition Problems
Consider the problem of partitioning a group of b indistinguishable objects into subgroups, each of size at leastl and at most u. The objective is to minimize the additive separable cost of the partition, where the cost associated with a subgroup of size j is c(j). In the case that c(.) is convex, we show how to solve the problem in O(log u-/ + 1) steps. In the case that c(.) is concave, we sol...
متن کاملValued Constraint Satisfaction Problems: Hard and Easy Problems
In order to deal with over-constrained Constraint Satisfaction Problems, various extensions of the CSP framework have been considered by taking into account costs, uncertainties, preferences, priorities...Each extension uses a specific mathematical operator (+;max : : :) to aggregate constraint violations. In this paper, we consider a simple algebraic framework, related to Partial Constraint Sa...
