Optimizing the branch number and branch length of radial drilling in high water cut low permeability reservoirs

Branch-and-cut Algorithms for Integer Programming, Branch-and-cut

Branch-and-cut methods are exact algorithms for integer programming problems. They consist of a combination of a cutting plane method with a branch-and-bound algorithm. These methods work by solving a sequence of linear programming relaxations of the integer programming problem. Cutting plane methods improve the relaxation of the problem to more closely approximate the integer programming probl...

Branch less, cut more and minimize the number of late equal-length jobs on identical machines

A simple greedy-type solution for a discrete optimization problem does not guarantee the optimality if the problem is sufficiently complicated. Dynamic programming is then a commonly used method, and a direct combinatorial algorithm is its reasonable alternative. Here we propose such an algorithm with some specific features, called branch less and cut more, abbreviated blesscmore. A blesscmore ...

Bilateral isolated cut of sensory branch of radial nerve.

Bilateral injuries of the sensory branch of the radial nerve (SBRN) usually occur as a result of tight-handcuff neuropathy. In this case we aimed to present bilateral isolated cut of SBRN resulting an injury mechanism that has not been reported in the literature previously. A male twenty-four years old, a worker in a glass factory, presented to our clinic. The dorsolateral skin of his wrists we...

Branch and Cut Algorithms

is the objective function to be optimized over P . Whenever all variables in (1.1) are restricted to be integral, the problem is known as a linear integer programming (IP) problem. Conversely, a pure linear programming (LP) problem results when all variables in (1.1) are restricted to be real valued. As is frequently the case for MIP, instead of attempting to optimize (1.3) directly over P , it...
