Table 3. Predicted optimal colony size as the function of the prey influx rate.

Optimization run: 1 2 3 4
Influx of prey: Inline graphic  = 0.25 prey/min Inline graphic  = 0.5 prey/min Inline graphic  = 1.0 prey/min Inline graphic  = 2.0 prey/min
Max. payoff found at: nColony*  = 93 ants nColony*  = 182 ants nColony*  = 360 ants nColony*  = 702 ants
The final payoff predicted: H(tmax)  = 2453.5 transported corpse per worker ant H(tmax)  = 3037.6 transported corpse per worker ant H(tmax)  = 3495.9 transported corpse per worker ant H(tmax)  = 3834.8 transported corpse per worker ant

The variable nColony * indicates the optimal value of nColony for a given value of Inline graphic, which was identified by a Powell optimization algorithm [51] for yielding the highest predicted value of H(tmax).
