## WHAT IS IT?

This is a model of nodes choosing between two options A (blue) and B (red). The two options have different payoffs. If a node chooses A, then it receives a payoff of a * (number of its neighbors who have also chosen A), similar for B. If BILINGUAL? is on, then a node can choose to be bilingual, but must pay a one-time cost of c in order to do so. Then it can reap the payoffs for both friends who chose A and friends who chose B. A and B could be e.g. calling plans, IM chat clients, even sports that nodes are coordinating their choices around.

## HOW IT WORKS

There are 4 different topologies, Lada's Facebook network from 2008, two examples from Chapter 19 of Easley and Kleinberg, and finally a ring lattice. You can setup each in turn to see the effect of topology on cascades. 

## HOW TO USE IT
To randomly initialize opinions with INIT-PROB-BLUE being blue, click on ALLOC OPINION.

Then set the payoffs for blue (A) and red (B), as well as a cost c for being bilingual if BILINGUAL? is on.

Click on UPDATE to see nodes update their opinions to maximize their utility.

To seed just a select few nodes with red and blue choices:
Click on SELECT-RED and click on the nodes you will seed with the red opinion. Click on SELECT-RED again to stop the selection process. Do the same with SELECT-BLUE. 

Then run the model, using either simple or complex contagion. You can slow things down by moving the speed slider up top.


## MAKING IT INTO A GAME

Challenge a friend. Have them pick two red nodes, and you pick two blue nodes. Update the nodes' choices. Whose opinion wins out?
