APX是approximable(可近似的)的缩写,在复杂度理论中,APX类问题是允许多项式时间近似算法且近似比在常数范围内的NP优化问题的集合,这种多项式时间复杂度且近似比(approximation ratio)在常数范围近似算法也称为constant-factor approximation algorithms。简单来说,这类问题具有在最优结果一定百分比内的高效算法。例如,在装箱...

Constant-factor polynomial-time approximation algorithms were proposed for CARP with triangle inequality, while CARP was claimed to be NP-hard to approximate within any constant factor in general. Correcting this claim, we show that any factor α approximation for CARP with triangle inequality yields ...

Constant-factor approximation for minimum-weight (connected) dominating sets in unit disk graphs For a given graph with weighted vertices, the goal of the minimum-weight dominating set problem is to compute a vertex subset of smallest weight such that each vertex of the graph is contained in the...
Here we provide an alternative implementation of the core idea from [DGKS18] with the main goal of developing a simpler constant-factor approximation algorithm with sub-quadratic run-time, while achieving the best possible bounds. To obtain our results, we need to generalize the problem to the...
