On the Approximability of External-Influence-Driven Problems
Panagiotis Aivasiliotis, Aris Pagourtzis
Domination problems in general can capture situations in which some entities have an effect on other entities (and sometimes on themselves). The usual goal is to select a minimum n…
Approximating Subset Sum Ratio via Partition Computations
Giannis Alonistiotis, Antonis Antonopoulos, Nikolaos Melissinos +3
We present a new FPTAS for the Subset Sum Ratio problem, which, given a set of integers, asks for two disjoint subsets such that the ratio of their sums is as close to as possi…
Faster Algorithms for -Subset Sum and Variations
Antonis Antonopoulos, Aris Pagourtzis, Stavros Petsalakis +1
We present new, faster pseudopolynomial time algorithms for the -Subset Sum problem, defined as follows: given a set of positive integers and targets $t_1, \ldots, t…
Approximation Schemes for Subset Sum Ratio Problems
Nikolaos Melissinos, Aris Pagourtzis, Theofilos Triommatis
We consider the Subset Sum Ratio Problem (), in which given a set of integers the goal is to find two subsets such that the ratio of their sums is as close to~1 as possible, a…
A Faster FPTAS for the Subset-Sums Ratio Problem
Nikolaos Melissinos, Aris Pagourtzis
The Subset-Sums Ratio problem (SSR) is an optimization problem in which, given a set of integers, the goal is to find two subsets such that the ratio of their sums is as close to 1…
