Multi-Agent Grid

This allows incorporation of:

Measurement Complications

New Measures: Aggregate

New Measures: Individual-level

Display complications

Grid cells now may have multiple members.

Solution: colors indicate summary indicators of opinions of agents within a cell.

Axelrod replication 1: typical outome
Axelrod replication 2: diversity?

Parochialism doesn't do much

Parochialism: probability of choosing discussant from own cell.

Parochialism = 0.50

    Features = 5

    Features = 10 stage 1
                     stage2
                     stage3
                     stage4

Parochialism=0.99  same result
 

Multi-Neighborhood Model

Agents from separate Nhoods might interact within the workplace.


Geographical dispersal allows

Importance of "Scheduling" concepts.

Agent movement allows them to: Our strategy:

Implementation

Dynamic Decentralized Scheduling (various)

Baseline model: Scheduling within Axelrod paradigm

    Same result with 5 neighborhoods
