NAME

       anemotaxis - directional search on a plane.

SYNOPSIS

       anemotaxis  [--display  host:display.screen]  [--visual  visual] [--window] [--root] [--window-id number]
       [--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
       trying 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.

       --window-id number
               Draw on the specified 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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
