摘要
We give sufficient conditions for deriving moderately exponential and/or parameterized time approximation schemata (i.e., algorithms achieving ratios 1 +/- epsilon, for arbitrarily small epsilon) for broad classes of combinatorial optimization problems via a well-known technique widely used for deriving exact algorithms, namely the branching tree pruning.
