Utilities

Module containing a host of useful functions that do not fall into more explicit categories.

Util.binaryCounter(bits)

Creates a generator that will count through all possible values for a set number of bits. Returned in counting order. For instance, binaryCounter(3) will yield, 000, 001, 010, 011 ... 110, 111.

Parameters:

• bits The number of bits in the binary counter.

Util.classMethods(classType)

Given a class type, return a dictionary mapping string names of that class’s methods to the actual method. For instance classMethod(LTGA)['twoParentCrossover'] will return the twoParentCrossover function.

Parameters:

• classType: Specifies what class to retrieve methods for.

Util.loadConfiguration(filename, fileMethod=<built-in function open>)

Loads a json from the given file name. Optional file method allows for compressed files.

Parameters:

• filename: The relative path to the file to be loaded.
• fileMethod: Handler to use to open the file. Defaults to regular open.

Util.loadConfigurations(filenames, fileMethod=<built-in function open>)

Given a list of file names, create a single dictionary containing all of their contents. Repeated keywords will override previously encountered values. Optional file method allows for compressed files.

Parameters:

• filenames: A list of relative paths to the files to be loaded.
• fileMethod: Handler to use to open the file. Defaults to regular open.

Util.meanstd(data)

Returns the mean and standard deviation of the given data.

Parameters:

• data: The data to find the mean and standard deviation of.

Util.median(data, default=0)

Given a data set, return the median value.

Parameters:

• data: The data to find the median of.
• default: If data contains no information, what value should be returned. Defaults to 0.

Util.moduleClasses(module)

Given a module, return a dictionary mapping string names of that module’s classes to the actual classes. For instance moduleClasses(FitnessFunction)['DeceptiveTrap'] will return the DeceptiveTrap class.

Parameters:

• module: Specifies what module to retrieve classes for.

Util.randomBitString(length)

Generate and return a random list of 0s and 1s.

Parameters:

• length: The length of the list to be generated.

Util.saveConfiguration(filename, data, fileMethod=<built-in function open>)

Writes a block of json-able data to the specifed file path.

Parameters:

• filename: The relative path to the file to be written to.
• data: Data that can be converted to a json. IE dictionaries and lists.
• fileMethod: Handler to use to open the file. Defaults to regular open.

Util.saveList(filename, data)

Write out a list of jsons in a more human readable way than saveConfiguration.

Parameters:

• filename: The relative path to the file to be written to.
• data: A list of json-able data to be written
