Questions tagged [agent-based-modeling]

Agent-based modeling is a computer simulation method where agents make decisions based on their interactions with each other and their environment. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming.

From Wikipedia:

An agent-based model (ABM) (also sometimes related to the term multi-agent system or multi-agent simulation) is a class of computational models for simulating the actions and interactions of autonomous agents (both individual or collective entities such as organizations or groups) with a view to assessing their effects on the system as a whole. It combines elements of game theory, complex systems, emergence, computational sociology, multi-agent systems, and evolutionary programming. Monte Carlo Methods are used to introduce randomness. ABMs are also called individual-based models.

Store data snapshots from an agent-based Matlab simulation

I'm writing an agent-based simulation in MATLAB in which agents play a game in rounds, selling stuff to each other. Pretty much everything (agents, items, locations, contracts...) is implemented as an object using MATLAB's OOP functionalities. Every…

Is it possible to use Agent Based Modelling tools such as Netlogo to do network simulation (e.g TCP)

I intend to model using Netlogo. However, I haven't seen any solid reference to using Netlogo for network simulations. I would like to check for simple network parameters like throughput and how changes in agent-set (Network node in the case) can…

Can I automate the assignment of attributes to agents in MESA without having to manually name each attribute?

I have a set of attributes (in form of a dataframe). Columns representing agents and rows representing attributes. Not all agents have all attributes, which means I can't manually name and assign the attributes or it'll be messy and hard to…
