exportNKFunction: Export/import (rM)NK-landscapes

In jakobbossek/smoof: Single and Multi-Objective Optimization Test Functions

Export/import (rM)NK-landscapes

Description

NK-landscapes and rMNK-landscapes are randomly generated combinatorial structures. In contrast to continuous benchmark function it thus makes perfect sense to store the landscape definitions in a text-based format.

Usage

exportNKFunction(x, path)

importNKFunction(path)

Arguments

x	[smoof_function] NK-landscape of rMNK-landscape.
path	[character(1)] Path to file.

Details

The format uses two comment lines with basic information like the package version, the date of storage etc. The third line contains \rho, M and N separated by a single-whitespace. Following that follow epistatic links from which the number of epistatic links can be attracted. There are M * N lines for a MNK-landscape with M objectives and input dimension N. The first N lines contain the links for the first objective an so on. Following that the tabular values follow in the same manner. For every position i = 1, \ldots, N there is a line with 2^{K_i + 1} values.

Note: exportNKFunction overwrites existing files without asking.

Value

Silently returns TRUE on success.
