WebMay 13, 2024 · 3. It is a well-known fact that, for a graph, the greedy coloring algorithm does not always return the most optimal coloring. That is, it strongly depends on the ordering of the vertices as they are colored. I was trying to understand what exactly about a particular vertex ordering makes the GCA mess up. WebI'll try to rephrase your comment correctly: If you take an optimal solution, you can turn it into the greedy solution by shiting only. Since shifting does not change the number of firemen, we deduce that the greedy solution has exactly as many firemen as some optimal solution. Therefore, the greedy solution is optimal too. $\endgroup$ – WebMar 20, 2024 · The employment of “greedy algorithms” is a typical strategy for resolving optimisation issues in the field of algorithm design and analysis.
