Abstract
A system described herein may provide a technique for the generation of a node map using contraction hierarchy techniques in a manner that accounts for multi-link constraints. Multi-link constraints may include a sequence of two or more links through the node map, and paths that include such multi-link constraints may be associated with an additional cost based on such inclusion. Shortcut links that represent paths through nodes contracted out of the node map may be associated with portions of multi-link constraints. Paths through such shortcut links, where such paths include the remainder of the multi-link constraint, may be considered as including the multi-link constraint, and the cost of such paths may be calculated accordingly. The costs of links and/or paths, including paths that include multi-link constraints, may be used in determining a path from a source node to a target node of the node map.
