Abstract
Most combinatorial optimization problems are NP-hard, and require computation exponential to the problem size. How can we solve difficult tree-search problems approximately, using the analytical results of their average-case complexity? The answer to this question leads to a new approximation approach, the topic of this chapter. This new method makes use of the complexity transitions of branch-and-bound on incremental random trees, and is referred to as ε-transformation.
