NAME
       anemotaxis - directional search on a plane.

SYNOPSIS
       anemotaxis  [-display  host:display.screen]  [-visual  visual]  [-window]  [-root]  [-delay  number]  [-distance  number] [-sources number]
       [-searchers number] [-fps]

DESCRIPTION
       The program demonstrates a search algorithm designed for locating a source of odor in turbulent atmosphere. 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 try-
       ing to capture the sources.

OPTIONS
       -visual visual
	       Specify which visual to use.  Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -delay number
	       Per-frame delay, in microseconds.  Default: 20000 (0.02 seconds.).

       -distance number
	       Max initial distance to the source .  10 - 250.	Default: 40.

       -sources number
	       Max number of sources.  Default: 25.

       -searchers number
	       Max number of searchers. Default: 25.

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT
       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
