Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| decide communication via alpha/beta/gamma reward estimates (ConTaCT) instead of communicating before using every new observation (RooC) | multi-agent grid rescue · 10x10 grid, 5 agents, 50 trials | total # communications: 112 -> 43 | Helped |
| ConTaCT vs RooC task success | multi-agent grid rescue · 10x10 grid, 5 agents, 50 trials | successful tasks (%): 78 -> 70 | Hurt |
| allow local replanning with unshared information and communication (ConTaCT) vs no communication | multi-agent grid rescue · 10x10 grid, 5 agents, 50 trials | successful tasks (%): 52 -> 70 | Helped |
| ConTaCT vs RooC across grid sizes and communication costs | multi-agent grid rescue · all grids | communication reduction: more than 60% reduction | Helped |
| ConTaCT vs NC on large 25x25 grid | multi-agent grid rescue · 25x25 grid, 5 agents, 20 trials, -Ric=1 | successful tasks (%): 35 -> 35 | No clear effect |
