| 4 | \brief Application Arena - Interaction of Mulptiple Participants |
---|
| 5 | |
---|
| 6 | Arena is a space in which participants (agents) live, there is one data source, arbitrary number of agents which communicate between each other. |
---|
| 7 | |
---|
| 8 | \section ex Matlab usage |
---|
| 9 | Execute command: |
---|
| 10 | \code |
---|
| 11 | >> arena(DS, {A1,A2,...},experiment,logger); |
---|
| 12 | \endcode |
---|
| 13 | where DS is a valid datasource and A1,... are agents and logger (optional) specified by their corresponding structures. |
