Detailed Description

The Sum of Different Powers function is unimodal.

Its optimal parameter = (0, ..., 0) and optimal function value = 0.

\[ f(x_1 \cdots x_n) = \sum_{i=1}^n |x_i|^{(i+1)} \]

\[ -1.00 \leq x_i \leq 1.00 \]

\[ \text{minimum at }f(0, \cdots, 0) = 0 \]

Constructor & Destructor Documentation

◆ sum_of_different_powers_function()

pass::sum_of_different_powers_function::sum_of_different_powers_function ( const arma::uword  dimension)
explicit
