Examples of aima.core.environment.map.ExtendableMap

aima.core.environment.map.ExtendableMap
Implements a map with locations, distance labeled links between the locations, straight line distances, and 2d-placement positions of locations. Locations are represented by strings and travel distances by double values. Locations and links can be added dynamically and removed after creation. This enables to read maps from file or to modify them with respect to newly obtained knowledge. @author Ruediger Lunde

     * Configures a scenario and a list of destinations. Note that for route
     * finding problems, the size of the list needs to be 1.
