General settings
General settings are the same for all algorithms.
z-D
This parameter controls the third dimension for only 2D benchmarks.
- auto: The depth will be calculated upon the blocks in the benchmark.
- manual: All blocks will have the given depth.
cost criteria
These are the cost criteria which can be calculated for a specific floorplan. One of these must be selected.
weight factors
These factors correspond with the cost criteria above. The calculated sum of the criteria is normalized to 1. With these factors the influence of one criteria can be adjusted. The sum of the weight factors must be 1 otherwise there occurs an error.
norm values
To calculate the sum of the cost criteria they must be normalized. The normalization is mostly done to the mean value of the criteria found by a Monte Carlo search. This values are saved in a database. If the database does not exist or the norm value was not yet searched, the program will automaticly switch to the estimate option and runs a short search for the mean value.
- database: Use norm value from database.
- estimate: Runs a short search for the mean value.
samples for norm value
This parameter sets the limit for the search of the mean value.
settings of Evolutionary Algorithm
parents
This parameter sets the number of parent individuals for each generation.
children
This parameter sets the number of children created by a recombination of two parent individuals.
generations
This parameter sets the number of generations created.
settings of Great Deluge Algorithm
vapor samples
This parameter sets the samples of searched solution after a vaporization before end the optimization
vapor value
This parameter sets the decreasing value of the critical value after a better solution was found.
settings of Monte Carlo Algorithm
samples
This parameter sets the number of random solutions.
settings of Simulated Annealing Algorithm
correct factor
This is a value for the difference of the sum between two solutions. At the temperatur Tend solutions with this difference will be accepted with a propability of 10%. To find the suitable option for this parameter you must run several different settings.
Tsteps
This parameter sets the steps between Tstart and Tend.
Tsamples
This parameter sets the solutions created each step.
Tstart
This parameter sets the start temperature.
Tend
This parameter sets the end temperature.
