1. Reinforcement learning for improved local search : Applied to the graph coloring problem
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The graph coloring problem (GCP) is an important combinatorial optimization problem (COP) with various applications and a simple formulation: to assign colors to vertices in a graph such that no adjacent vertices share a color. The GCP is NP-hard, and in order to solve it within a reasonable time frame, heuristic local search (LS) based algorithms are commonly used. LÄS MER
2. Discrete Flower Pollination Algorithm for the Graph Coloring Problem
Kandidat-uppsats, KTH/DatavetenskapSammanfattning : The graph coloring problem (GCP) is a famous NP-hard problem applicable to many real-world problems. The Flower Pollination Algorithm (FPA) is a relatively recently developed algorithm based on the pollination-behaviors of flowers. It has seen great results in single- and multi-objective optimization in continuous search spaces. LÄS MER
3. Upper bounds on the star chromatic index for bipartite graphs
Kandidat-uppsats, Linköpings universitet/Matematik och tillämpad matematik; Linköpings universitet/Tekniska fakultetenSammanfattning : An area in graph theory is graph colouring, which essentially is a labeling of the vertices or edges according to certain constraints. In this thesis we consider star edge colouring, which is a variant of proper edge colouring where we additionally require the graph to have no two-coloured paths or cycles with length 4. LÄS MER
