  2. 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

  3. 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.

    SYMPHONY is a callable library which implements both sequential and parallel versions of branch, cut and price to solve MILPs. A branch, cut and price algorithm is similar to a branch and bound algorithm but additionally includes cutting-plane methods and pricing algorithms. The user of the library can customize the algorithm in any number of ...

  5. 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.

    However, there is a fractional solution in which each set is assigned the weight 1/2, and for which the total value of the objective function is 3/2. Thus, in this example, the linear programming relaxation has a value differing from that of the unrelaxed 0–1 integer program.

    From September 2011 to December 2012, if you bought shares in companies when William J. DeLaney joined the board, and sold them when he left, you would have a 16.3 percent return on your investment, compared to a 18.4 percent return from the S&P 500.

  8. Lambert W function - Wikipedia

    en.wikipedia.org/wiki/Lambert_W_function

    The branch point for the principal branch is at z = − ⁠ 1 / e ⁠, with a branch cut that extends to −∞ along the negative real axis. This branch cut separates the principal branch from the two branches W −1 and W 1. In all branches W k with k ≠ 0, there is a branch point at z = 0 and a branch cut along the entire negative real axis.

    A bright spot for Diageo. While growth has slowed for distillers and brewers in the past year, Diageo’s Guinness has gone against the trend, noted Verushka Shetty, an equity analyst at Morningstar.
