Options for the forest-fire simulation

Options for `forest' and `forestnc':

-w#

Set the system width to # sites. # must be divisible by 32.

-h#

Set the system height to # sites.

-f#

Set f/p to #/1000000. This option has no effect if also the option `-g' is specified.

-s

Show the state of the system on an X11 display. This option has no effect if also the option `-g' is specified.

-d

Resume the simulation after the point stored in the status file.

-e

Evaluate information stored in the status file, e.g. produce the result files that would otherwise only be created at the end of the simulation.

-i#

Set the total number of iterations (equilibration time plus data collection) to # global time units.

-x#

Set the number of initial iterations for equilibration to # global time units. During these initial iterations no quantities beyond the global density are evaluated. This option has no effect if also the option `-g' is specified.

-m#

Limit the distance y at which to evaluate C(y) by #. Larger intervals of distances need more CPU time such that this option can be used to make the simulation run faster (compare also the remark in the general description of the program). This option has no effect if also the option `-g' is specified.

-l

Divide the system into plaquettes of size 16x16 and compute the local density distribution on them. This option has no effect if also the option `-g' is specified.

-L#

Divide the system into plaquettes of size specified by # and compute the local density distribution on them. The following values of # are permitted:
1: 256x1 plaquettes.
2: 128x2 plaquettes.
4: 64x4 plaquettes.
8: 32x8 plaquettes.
This option has no effect if also the option `-g' is specified.

Options only valid for `forest':

-g

Generate configurations according to the density distribution in the file `dens_fluc' instead of using the dynamical rules of the full model. In this case, `-i#' specifies the number of configurations to be created and some other options become meaningless (see above).
