Shekel functions
Description
Single-objective test function based on the formula
f(\mathbf{x}) = -\sum_{i=1}^{m} \left(\sum_{j=1}^{4} (x_j - C_{ji})^2 + \beta_{i}\right)^{-1}
.
Here, m \in \{5, 7, 10\} defines the number of local optima, C is a 4 x 10 matrix
and \beta = \frac{1}{10}(1, 1, 2, 2, 4, 4, 6, 3, 7, 5, 5) is a vector. See https://www.sfu.ca/~ssurjano/shekel.html
for a definition of C.
Usage
makeShekelFunction(m)
Arguments
m
[numeric(1)]
Integer parameter (defines the number of local optima).
Possible values are 5, 7 or 10.
Value
An object of class SingleObjectiveFunction, representing the Shekel Functions.
