  2. Branch and bound - Wikipedia

    en.wikipedia.org/wiki/Branch_and_bound

    The following is the skeleton of a generic branch and bound algorithm for minimizing an arbitrary objective function f. [3] To obtain an actual algorithm from this, one requires a bounding function bound, that computes lower bounds of f on nodes of the search tree, as well as a problem-specific branching rule.

  3. Couenne - Wikipedia

    en.wikipedia.org/wiki/Couenne

    Couenne is an implementation of a branch-and-bound where every subproblem is solved by constructing a linear programming relaxation to obtain a lower bound. Branching may occur at both continuous and integer variables, which is necessary in global optimization problems.

  4. Branch and cut - Wikipedia

    en.wikipedia.org/wiki/Branch_and_cut

    Branch and cut [1] is a method of combinatorial optimization for solving integer linear programs (ILPs), that is, linear programming (LP) problems where some or all the unknowns are restricted to integer values. [2] Branch and cut involves running a branch and bound algorithm and using cutting planes to tighten

  5. Interval contractor - Wikipedia

    en.wikipedia.org/wiki/Interval_contractor

    In mathematics, an interval contractor (or contractor for short) [1] associated to a set is an operator which associates to a hyperrectangle [] in another box ([]) of such that the two following properties are always satisfied:

  6. Maximum satisfiability problem - Wikipedia

    en.wikipedia.org/wiki/Maximum_satisfiability_problem

    The MAX-SAT problem is OptP-complete, [1] and thus NP-hard, since its solution easily leads to the solution of the boolean satisfiability problem, which is NP-complete. It is also difficult to find an approximate solution of the problem, that satisfies a number of clauses within a guaranteed approximation ratio of the optimal solution.

    Cowlick vs. Balding: Key Differences. A cowlick differs from a bald spot in a couple key ways.. First, a cowlick is a natural, normal feature of your scalp that occurs as a result of your genes.

  8. Branch and price - Wikipedia

    en.wikipedia.org/wiki/Branch_and_price

    Branch and price is a branch and bound method in which at each node of the search tree, columns may be added to the linear programming relaxation (LP relaxation). At the start of the algorithm, sets of columns are excluded from the LP relaxation in order to reduce the computational and memory requirements and then columns are added back to the LP relaxation as needed.
