RoutingOptions.MaxAbs Property

Gets a heuristic delegate function that returns max(dx, dy) as a cost evaluation of the distance between two pieces of the routing grid.

 Syntax

C#

public static RouteHeuristics MaxAbs { get; }

Visual Basic

Public Shared ReadOnly Property MaxAbs As RouteHeuristics

 Property Value

A predefined RouteHeuristics delegate instance.

 Remarks

While generating a path, the routing algorithm evaluates pieces of the routing grid adjacent to the current one. It takes into account the cost for passing trough a piece and adds to that cost a heuristic value calculated by a RouteHeuristics delegate function. So the smaller heuristic value a piece has, the greater the chance the found route to go through that piece.

MaxAbs is a predefined delegate that assigns to pieces the higher value from the horizontal or vertical -only distances between a piece and the target. MaxAbs can be assigned to the RouteHeuristics property. By returning smaller values than the default heuristic function Distance, it makes the prediction part of the routing algorithm have less impact on the evaluated routes. That might lead to slower path-finding, but the real cost functions would have greater impact and thus the quality of the found routes could be higher.
