  2. Price floor - Wikipedia

    en.wikipedia.org/wiki/Price_floor

    A government-set minimum wage is a price floor on the price of labour. A price floor is a government- or group-imposed price control or limit on how low a price can be charged for a product, [1] good, commodity, or service. It is one type of price support; other types include supply regulation and guarantee government purchase price.

  3. Branch and price - Wikipedia

    en.wikipedia.org/wiki/Branch_and_price

    The branch and price method can be used to solve problems in a variety of application areas, including: Graph multi-coloring. [3] This is a generalization of the graph coloring problem in which each node in a graph must be assigned a preset number of colors and any nodes that share an edge cannot have a color in common. The objective is then to ...

    succinct versions of many graph problems, with graphs represented as Boolean circuits, [43] ordered binary decision diagrams [44] or other related representations: s-t reachability problem for succinct graphs. This is essentially the same as the simplest plan existence problem in automated planning and scheduling. planarity of succinct graphs

  5. Price controls - Wikipedia

    en.wikipedia.org/wiki/Price_controls

    A government-set minimum wage is a price floor on the price of labour. A price floor is a government- or group-imposed price control or limit on how low a price can be charged for a product, [24] good, commodity, or service. A price floor must be higher than the equilibrium price in order to be effective. The equilibrium price, commonly called ...

  6. List of NP-complete problems - Wikipedia

    en.wikipedia.org/wiki/List_of_NP-complete_problems

    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. A related problem is to find a partition that is optimal terms ...

  7. Minimum-cost flow problem - Wikipedia

    en.wikipedia.org/wiki/Minimum-cost_flow_problem

    A related problem is the minimum cost circulation problem, which can be used for solving minimum cost flow. The minimum cost circulation problem has no source and sink; instead it has costs and lower and upper bounds on each edge, and seeks flow amounts within the given bounds that balance the flow at each vertex and minimize the sum over edges ...

    en.wikipedia.org/wiki/General_Problem_Solver

    General Problem Solver (GPS) is a computer program created in 1957 by Herbert A. Simon, J. C. Shaw, and Allen Newell (RAND Corporation) intended to work as a universal problem solver machine. In contrast to the former Logic Theorist project, the GPS works with means–ends analysis .
