With r1 = a - t a / T, each coordinate moves x + r1 sin(r2) |r3 P - x| when
r4 < 1/2 and with cos(r2) otherwise; r2 ~ U(0, 2 pi), r3 ~ U(0, 2).
Usage
SineCosineAlgorithm(f, bounds, a = 2, n_pop = 20, max_iter = 200, seed = 0)
Arguments
- f
Objective to minimise.
- bounds
List of c(low, high) pairs or a two-column matrix.
- a
Initial r1.
- n_pop
Population size.
- max_iter
Iterations.
- seed
Philox seed.
Value
list(x, fun, estimate, history, n_fev, method).
