Abstract:

Symmetric submodular maximization is an important class of combinatorial optimization problems, including MAX-CUT on graphs and hyper-graphs. The state-of-the-art algorithm for the problem over general constraints has an approximation ratio of 0.432 [16]. The algorithm applies the canonical continuous greedy technique that involves a sampling process. It, therefore, suffers from high query complexity and is inherently randomized. In this paper, we present several efficient deterministic algorithms for maximizing a symmetric submodular function under various constraints. Specifically, for the cardinality constraint, we design a deterministic algorithm that attains a 0.432 ratio and uses O(kn) queries. Previously, the best deterministic algorithm attains a 0.385−ϵ ratio and uses [Formula presented] queries [12]. For the matroid constraint, we design a deterministic algorithm that attains a 1/3−ϵ ratio and uses O(knlog⁡ϵ−1) queries. Previously, the best deterministic algorithm can also attain 1/3−ϵ ratio but it uses much larger O(ϵ−1n4) queries [24]. For the packing constraints with a large width, we design a deterministic algorithm that attains a 0.432−ϵ ratio and uses O(n2) queries. To the best of our knowledge, there is no deterministic algorithm for the constraint previously. The last algorithm can be adapted to attain a 0.432 ratio for single knapsack constraint using O(n4) queries. Previously, the best deterministic algorithm attains a 0.316−ϵ ratio and uses O˜(n3) queries [2]. © 2025 Elsevier B.V.
