Connect
This rule connects nodes that are within maxRange distance, but only if there are not too many obstacles separating their line of sight. The base idea is that line-of-sight distance and routing distance should not differ "too much", as captured by tolerance. tolerance measures the maximum allowed relative difference between the line-of-sight and the route distance. It's default 0.1 (10%) means that if LOS-distance is more than 10% shorter than route-distance, then the nodes are considered disconnected. Route distance is taken two-ways (to account for one-way roads) and the shortest one is considered (wireless signals do not need to follow one-way roads).
Properties
Functions
Produces a new neighborhood for specified node considering its position.
Some rules may require to be evaluated against multiple nodes until the situations gets consistent. For instance, a rule that connects the closest 10 nodes must be evaluated multiple times to get to the correct result (this is because a change in one neighbor may require a disconnection from another node to maintain exactly 10 connections). Most rules do not need such machinery (e.g., connecting to nodes within some statically defined range).
