2choosable
2choosable is a term used primarily in the context of graph theory, a branch of mathematics concerned with the study of graphs—structures made up of vertices (or nodes) connected by edges. The concept of 2choosability pertains to graph coloring, specifically list coloring or choosability, where each vertex is assigned a list of allowable colors.
A graph is said to be 2choosable if, for any assignment of lists of two colors to
The concept of 2choosability is significant because it relates to the flexibility of coloring graphs under
In general, certain classes of graphs, such as bipartite graphs, are known to be 2choosable, while others
To summarize, 2choosable refers to graphs that can be properly colored from any list assignment of two
