# DLIFE soup configuration file.

#----------------------------------------------------------------------
# The size of the soup (in bytes).
#
# This parameter must be a power of 2. If you change this parameter,
# then you will have to reinitialize the soup image. You cannot load
# a soup image from one version of the program into another version
# with a different soup size.

# Failure probabilities.
#
# All probabilities are expressed in the form ``1 in N'' where N is
# an integer between 1 and about 4 billion. Larger values of N means
# the event is rarer. You can dramatically change the behaviour of
# the environment by changing these parameters - from a highly-
# irradiated soup similar to the early earth (and NOT supporting
# life) - to an almost completely stable soup free from almost any
# mutation.

# The probability that fetching a value from the soup will fail.

soup_fetch_failure          1000000

# The probability that the program counter will fail to increment
# after an instruction has been executed.

inc_pc_failure              1000000

# The overall probability that an instruction will fail to execute
# correctly.

insn_exec_failure           1000000

# The probability that the access control mechanisms (which govern
# what addresses a cell may write to) will fail. It is OK to have
# this probability quite large (ie. small N) so that cells may try
# to ``invade'' other cells.

access_control_failure      10

# The probability that a newly created cell isn't initialized correctly -
# ie. that the registers and stack don't start off at zero.

cell_initialization_failure 1000000

#----------------------------------------------------------------------
# Grim reaper configuration.
#
# These parameters control when and for how long the grim reaper
# comes to life and kills off sick cells. These two parameters are
# expressed as percentages of soup used (ie. ``80'' means the soup
# is 80% full).

# The grim reaper is invoked when the soup is this full.

reaper_invoke_threshold     80

# The grim reaper runs until the soup is this full (and then
# goes back to sleep again).
