The odor is convected by wind +which has a constant mean direction and fluctuations around it. The +searcher is able to sense the odor and determine local instantaneous +wind direction. The goal is to find the source in the shortest mean +time. Some animals face this task to find mates, food, home etc. They +exhibit very particular, zigzagging search trajectories. + +This is modeled as a search on a discrete two-dimensional lattice. The +source releases particles that drift with constant velocity in one +direction and walk randomly in the other direction. The searcher knows +if it hit a particle, and if so, particle's position one time step +earlier (local wind direction). The program paints sources and +particles released by them as well as trajectories of searchers who are +trying to capture the sources. +.SH OPTIONS +.TP 8 +.B \-visual \fIvisual\fP +Specify which visual to use.
