A Hierarchical Social Metaheuristic for the Max-Cut Problem

چکیده
This paper introduces a new social metaheuristic for the Max-Cut problem applied to a weighted undirected graph. This problem consists in finding a partition of the nodes into two subsets, such that the sum of the weights of the edges having endpoints in different subsets is maximized. This NP-hard problem for non planar graphs has several application areas such as VLSI and ASICs CAD. The hierarchical social (HS) metaheuristic here proposed for solving the referred problem is tested and compared with other two metaheuristics: a greedy randomized adaptive search procedure (GRASP) and an hybrid memetic heuristic that combines a genetic algorithm (GA) and a local search. The computational results on a set of standard test problems show the suitability of the approach.

Region Merging for Severe Oversegmented Images Using a Hierarchical Social Metaheuristic
This paper proposes a new evolutionary region merging method to improve segmentation quality result on oversegmented images. The initial segmented image is described by a modified Region Adjacency Graph model. In a second phase, this graph is successively partitioned in a hierarchical fashion into two subgraphs, corresponding to the two most significant components of the actual image, until a t...
متن کاملTop-Down Evolutionary Image Segmentation Using a Hierarchical Social Metaheuristic
This paper presents an application of a hierarchical social (HS) metaheuristic to region-based segmentation. The original image is modelled as a simplified image graph, which is successively partitioned into two regions, corresponding to the most significant components of the actual image, until a termination condition is met. The graph-partitioning task is solved as a variant of the min-cut pr...
متن کاملImproving image segmentation quality through effective region merging using a hierarchical social metaheuristic
This paper proposes a new evolutionary region merging method in order to efficiently improve segmentation quality results. Our approach starts from an oversegmented image, which is obtained by applying a standard morphological watershed transformation on the original image. Next, each resulting region is represented by its centroid. The oversegmented image is described by a simplified undirecte...
متن کاملA Graph-Based Image Segmentation Algorithm Using a Hierarchical Social Metaheuristic
This chapter proposes a new evolutionary graph-based image segmentation method to improve quality result. Our approach is quite general and can be considered as a pixel or region based segmentation technique. What is more important is that they (pixels or regions) are not necessarily adjacent. It starts from an image described by a simplified undirected weighted graph where nodes represent eith...
متن کاملA VNS Metaheuristic with Stochastic Steps for Max 3-Cut and Max 3-Section
A heuristic algorithm based on VNS is proposed to solve the Max 3-cut and Max 3-section problems. By establishing a neighborhood structure of the Max 3-cut problem, we propose a local search algorithm and a variable neighborhood global search algorithm with two stochastic search steps to obtain the global solution. We give some numerical results and comparisons with the well-known 0.836-approxi...
