readConfigurationsFile function

Read parameter configurations from a file

Reads a set of target-algorithm configurations from a file and puts them in irace format. The configurations are checked to match the parameters description provided.

readConfigurationsFile(filename, parameters, debugLevel = 0L, text)

Arguments

• filename: character(1)

  Filename from which the configurations should be read. The contents should be readable by read.table( , header=TRUE).

• parameters: ParameterSpace

  Data structure containing the parameter space definition. The data structure has to similar to the one returned by the function readParameters.

• debugLevel: integer(1)

  Larger values produce more verbose output.

• text: character(1)

  If file is not supplied and this is, then configurations are read from the value of text via a text connection.

Returns

A data frame containing the obtained configurations. Each row of the data frame is a candidate configuration, the columns correspond to the parameter names in parameters.

Details

Example of an input file:

# This is a comment line
param_1    param_2
    0.5  "value_1"
    1.0         NA
    1.2  "value_3"

The order of the columns does not necessarily have to be the same as in the file containing the definition of the parameters.
