Branch and cut

Branch and cut 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. Branch and cut involves running a branch and bound algorithm and using cutting planes to tighten the linear programming relaxations. Note that if cuts are only used to tighten the initial LP relaxation, the algorithm is called branch and cut. (Wikipedia).

Finding the length of a segment given the whole and part - Free Math Help - Online Tutor

👉 Learn how to find the missing measure of a segment. A segment is a line that has two endpoints. A segment can be subdivided into several portions. The length of the segment is the sum of all the sub-divisions of the segment. Thus, when given a segment sub-divided into portions, we can us

Set Theory (Part 15): Dedekind Cut Arithmetic

Please feel free to leave comments/questions on the video and practice problems below! In this video, we will set up arithmetic (addition and multiplication) for Dedekind cuts and thereby show that the real numbers form a complete ordered field. We will also prove some common laws of real
