Summary of state variables in our model.
| | State variable | Variable type | Description |
| | Agent memory | A set including multiple vectors | Agent memorized solutions, each of them is a vector (i.e., a point on a problem space) | | Agent current solution | A vector | The best solution in the agent’s memory | | Utility of agent current solution | A real number between 0.0 and 1.0 | The utility of the agent’s current solution | | Agent individual utility function | A formula based on given vectors and a vector in question | It gives an agent’s representation of a given problem space | | Group solution | A vector | A group’s current solution | | Utility of group solution | A real number between 0.0 and 1.0 | The utility of a group’s current solution | | Ratio of agreement | A real number between 0.0 and 1.0 | It represents group consensus on a proposed solution |
