2. Graph coloring - Wikipedia

   en.wikipedia.org/wiki/Graph_coloring

   Graph coloring. A proper vertex coloring of the Petersen graph with 3 colors, the minimum number possible. In graph theory, graph coloring is a special case of graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. In its simplest form, it is a way of coloring the ...

3. List coloring - Wikipedia

   en.wikipedia.org/wiki/List_coloring

   For a graph G, let χ(G) denote the chromatic number and Δ(G) the maximum degree of G.The list coloring number ch(G) satisfies the following properties.ch(G) ≥ χ(G).A k-list-colorable graph must in particular have a list coloring when every vertex is assigned the same list of k colors, which corresponds to a usual k-coloring.

4. List of NP-complete problems - Wikipedia

   en.wikipedia.org/wiki/List_of_NP-complete_problems

   Graph coloring [2] [3]: GT4 Graph homomorphism problem [3]: GT52 Graph partition into subgraphs of specific types (triangles, isomorphic subgraphs, Hamiltonian subgraphs, forests, perfect matchings) are known NP-complete. Partition into cliques is the same problem as coloring the complement of the given graph.

   Stranger Things has officially been a phenomenon since it debuted in 2016, with perhaps no greater indicator than the fact that it’s inspired more merchandise than any of us could ever buy, from ...

6. Register allocation - Wikipedia

   en.wikipedia.org/wiki/Register_allocation

   Graph-coloring allocation is the predominant approach to solve register allocation. [ 17 ] [ 18 ] It was first proposed by Chaitin et al. [ 4 ] In this approach, nodes in the graph represent live ranges ( variables , temporaries , virtual/symbolic registers) that are candidates for register allocation.

7. Interactive children's book - Wikipedia

   en.wikipedia.org/wiki/Interactive_children's_book

   Whether the hidden object is a hard-to-spot character, or an item specified by the author in a rhyming list is subject to the book or possibly the series of books it belongs to. Although it is not standard, these types of interactive children's books are sometimes published with a common theme such as Christmas or life on the farm.

8. NP-completeness - Wikipedia

   en.wikipedia.org/wiki/NP-completeness

   The concept of NP-completeness was introduced in 1971 (see Cook–Levin theorem), though the term NP-complete was introduced later. At the 1971 STOC conference, there was a fierce debate between the computer scientists about whether NP-complete problems could be solved in polynomial time on a deterministic Turing machine.

9. Edge coloring - Wikipedia

   en.wikipedia.org/wiki/Edge_coloring

   In graph theory, a proper edge coloring of a graph is an assignment of "colors" to the edges of the graph so that no two incident edges have the same color. For example, the figure to the right shows an edge coloring of a graph by the colors red, blue, and green. Edge colorings are one of several different types of graph coloring.
