WebBranch-and-Cut Overview. Before examining CBC in more detail, we tersely describe the basic branch-and-cut algorithm by way of example, (which should really be called branch-and-cut-and-bound) and show the major C++ class(es) in CBC related to each step. The major CBC classes, labeled (A) through (F), are described in the table below. Step 1. http://web.mit.edu/16.410/www/lectures_fall04/L18-19-IP-BB.pdf WebChromatic detects squash and rebase merges. Your baselines are preserved between branches, even when squashing or rebasing wipes the Git history. If you use the “squash” or “rebase” merge feature on Pull Requests, then a commit is created on your base branch that is not a descendant of the commits for the PR.
