MORe This network builder considers baseline homophily (McPherson2001). Additional to MGeoRsBaselineRadiusNetworkService it also completely links agent within a group context (in general, the agents parental context). Agents are linked as follows:

Connect every agent with all other agents within the same group context. This may not entirely reflect the agents' preferences regarding partner milieus. However, a group is as it is and may not be altered by the focal agent. Nevertheless an agent may choose the place he or she wants to live. These choices are represented in the market cell distributions the agent initialisation is based upon.
For every agent in the context
1. Fetch all agents within a given radius (SEARCH_RADIUS) from the focal agent (do not consider area boundaries).
2. For every potential partner that is not yet connected check according to milieu specific probability if it should be connected with focal agent. The approach to check the agents that are in the surroundings as they come considers the local milieu distribution and reflects baseline homophily. Applying milieu specific tie probabilities reflects inbreeding homophily.
3. If the number of required neighbours is not satisfied but all fetched agents checked, request more agents from geography within an extended radius (X_SEARCH_RADIUS) until maximum radius ( MAX_SEARCH_RADIUS) is reached.
Rewire: For each agent, check if every existing link should be rewired (with probability p_rewire) to a randomly chosen agent from the whole region that passes the milieu check (applying milieu tie probabilities ( p_links for every partnerMilieu). On purpose the new partner's milieu is not guaranteed to be the same as that of the original link: The partners within direct surroundings are coined by local milieu distributions (baseline homophly) and therefore do not entirely reflect the focal agent's preferences. Determining the milieu during rewiring anew may correct to milieu distributions of partners towards inbreeeding homophily and is desired.

Uses MGeographyWrapper.getSurroundingAgents(Object, double, Class) to fetch agents (all agents within the given radius of the given class). Internal: The BaselineDhhRadiusNetworkBuilder is based on DHH_ColCalc_Computer_Lifestyle.
