Configuration file (XML)_eac3

root element: EACIRC

Project-specific settings are added separate subtrees linked to the root element. Their structure is described in project documentation.

Back-end specific settings are added as separate subtrees linked to the root element (GATE_CIRCUIT, POLYNOMIAL_CIRCUIT). Their structure is described in back-end documentation.

• NOTES developer notes (descriptive only)
• MAIN
  • CIRCUIT_REPRESENTATION
    determines which back-end will be used
    1: using gate circuits
    2: using polynomially represented circuit
  • PROJECT
    determines which project will be used to generate test vectors
    Note: Particular project constatns can be found in project documentation.
  • EVALUATOR
    determines the algorithm to use when evaluating circuits
    Note: Evaluator constants and description can be found in evaluator description.
  • EVALUATOR_PRECISION
    value used by evaluator (typically a precision value, e.g. number of categories)
  • RECOMMENCE_COMPUTATION
    1: program recommences computation from saved state (=> implies load_initial_population)
    0: program starts from clean initial state
  • LOAD_INITIAL_POPULATION
    1: program load initial population from file
    0: program randomly creates initial population
  • NUM_GENERATIONS
    number of generation to compute in evolution
  • SAVE_STATE_FREQ
    how often to save state of the computaion (immediately after saving the state, GAlib is reseeded to retain determinism and repeatability)
  • CIRCUIT_SIZE_INPUT
    number of circuit input bytes (for all backend representations)
  • CIRCUIT_SIZE_OUTPUT
    number of circuit output bytes (for all backend representations)
• OUTPUTS
  • VERBOSITY
    0-4: How detailed should the debugging info be (logs, output files, ...). Detailed information about verbosity levels in outputs specification
  • INTERMEDIATE_CIRCUITS
    1: save best circuits from intermediate generations
    0: do not save intermediate circuits
  • ALLOW_PRUNNING
    1: when saving circuits, save also prunned version of each (version without useless functions and connectors)
    0: only save full circuits, do not prune
  • SAVE_TEST_VECTORS
    1: save all the generated test vectors to a binary file for further processing
    0: do not save test vectors to file
• RANDOM
  • USE_FIXED_SEED
    1: fixed seed loaded from these settings should be used
    0: initial system should be system-generated at the beginning of the computation
  • SEED
    numerical value of seed to use equal or less then ULONG_MAX (~4 294 967 295)
    seed value is ignored if 0 (even if USE_FIXED_SEED = 1)
  • BIAS_RNDGEN_FACTOR
    probability of generating 1 over 0 in bias RNG (number 0%-100%)
  • USE_NET_SHARE
    1: tries to invoke external commands mapping network share with random data (used on Metacentrum machines)
    0: do not try to map network share
  • QRNG_PATH
    path to files with random data, relative from the executed binary or absolute
    Note: Path must end with a directory separator.
    only first 10 MB of each file are used (or less if file is smaller)
    file names follow pattern Random.bin where 0 <= <= maxIndex and has left zeroes up to width of maxIndex
    more than one path can be entered, separated by semicolon (in this case, they are considered as alternatives)
  • QRNG_MAX_INDEX
    maximal index of random data file (not total number of files!)
• CUDA
  • ENABLED
    1: CUDA support enabled
    0: CUDA support disabled
  • TBD
• GA
  • EVOLUTION_OFF
    1: evolution is off, test vector generation and evolution is done every generation (=> implies load_initial_population)
    0: evolution on
  • POPULATION_SIZE
    number of genomes in a population
  • REPLACEMENT_SIZE
    number of individuals to replace each generation (use ~2/3 POPULATION_SIZE)
  • PROB_MUTATION
    probability of genome mutation (number between 0.0 and 1.0)
  • PROB_CROSSING
    probability of genome crossing (number between 0.0 and 1.0)
  • MUTATE_FUNCTIONS
    1: allow changing functions when performing mutation
    0: forbid changing functions
  • MUTATE_CONNECTORS
    1: allow changing connectors when performing mutation
    0: forbid changing connectors
• TEST_VECTORS
  • INPUT_LENGTH
    length of the test vectors in bytes
  • OUTPUT_LENGTH
    length of the expected outputs in bytes
    Note: This may be different than circuit output size.
  • SET_SIZE
    number of test vectors in a test set
  • SET_CHANGE_FREQ
    number of generations to wait to regenerate test vectors
  • SET_CHANGE_PROGRESSIVE
    1: change test vectors progressively, more often in the beginning and less often in the end
    0: change test vectors periodically as set by TEST_VECTOR_CHANGE_FREQ
    Note: Progressive test vector changing does not support state saving.
  • EVALUATE_BEFORE_TEST_VECTOR_CHANGE
    1: fitness data is written to file just before test vector change
    0: fitness data is written to file after changing test vectors
  • EVALUATE_EVERY_STEP
    evaluate population after every evolution step
    Note: By default, population is evaluated only when test vectors are regenerated.
