Ants use random numbers to direct their motion, and also to direct their actions.
Random Input for Motion and Object Manipulation Ants may move in any one of 8 directions on the lattice. The choice of direction thus requires 3 bits. Basic ants constantly consume this many bits at each time step to direct their motion. Complexity-seeking ants consume fewer random bits for motion since they do not change direction each time. This is shown in figure 6 .
