  • Beam search is a restricted, or modified, version of either a breadth-first search or a best-first search. It is restricted in the sense that the amount of memory available for storing the set of alternative search nodes is limited, and in the sense that non-promising nodes can be pruned at any step in the search (Zhang, 1999). The pruning of non-promising nodes is determined by problem-specific heuristics (Zhang, 1999). The set of most promising, or best alternative, search nodes is called the “beam” (Xu and Fern, 2007). Essentially, beam search is a forward-pruning, heuristic search.

  • The preceding local search algorithms maintain a single total assignment. This section considers algorithms that maintain multiple total assignments. The first method, beam search, maintains the best k assignments. The next algorithm, stochastic beam search, selects which assignments to maintain stochastically. In genetic algorithms, which are inspired by biological evolution, the k assignments forming a population interact to produce the new population. In these algorithms, a total assignment of a value to each variable is called an individual and the set of current individuals is a population.
