(1) Agent based modelthis model includes 3 parts :first :agent . This can be individual , firms. behaviours : how agents behave , in schelling's model that means the threshold of the people to move ou...

Colonel Blotto DefinationThis model's about strategic mismatch and allocation of the resources.It combines 3 parts. For example:Players : employeesFronts: each skills that employees ownResou...

What does randomness look like?Normal distributionUniform distributionHow to access someone's skill?outcome = a * luck + (1-a) * skilla is big if someone's outcome depends on luck. So we...

Polya processIn a urn model, suppose that we have 2 balls red and blue in a urn. Every time we can pick up a ball and return it back and put a same color of this ball into the urn. And we can draw 2...

Degreenumber of edges connected to a node. Average degree = 2*edges/nodesPathhow many edges between two specific nodes.Clustering coefficentHow many percentage of the triple nodes connected ...

Why cultures are different?Assume that we have a n*n square. Each block represent a person.Assumption 1 : we have several features to coordinate each feature has a trait. a trait looks like {1,2,2...

If we can set up a lyaponuv function for the model, then this system means it can go to equilibrium. F(x) is a lyaponuv function.Assumption1: F(x) has a maximum value.Assumption2:if x(t+1) != x(...

 In this part, i will introduce how to solve the problem.(1) PerspectivePerspective means how you encode the question. you can explain the question in many ways, but how you explain the question...

Percolation modelIf the model can be seen as a net, then we can use this model. For example, in information transmission, the y axis can be how many people will hear your information and the x axis ca...

Rational actor modelWe assume that(1)actor has his own objective(2)actor will optimize his objectiveThen we can predict what other people would do, Cause they're rational. Also we can also use this as...

Aggregation(1)Simple rules combine to form anything. In agent based model, just some simple rule that every agent follows would have a complicated outcome.(2)It from bit. Every difficult system would ...
