Popinitial_fixknots: Fixed-Knots Population Initializer

In GAReg: Genetic Algorithms in Regression

Fixed-Knots Population Initializer

Description

Initializes a population matrix for the fixed-knots GA. Each column is a feasible chromosome sampled by selectTau_uniform_exact.

Usage

Popinitial_fixknots(
  popSize,
  prange = NULL,
  N,
  minDist,
  Pb,
  mmax,
  lmax,
  fixedknots
)

Arguments

popSize	Integer; number of individuals (columns).
prange	Optional hyperparameter range (unused here).
N	Series length.
minDist	Integer minimum spacing between adjacent changepoints.
Pb	Unused placeholder (kept for compatibility).
mmax, lmax	Integers; maximum number of knots and chromosome length.
fixedknots	Integer; number of knots to place.

Value

Integer matrix of size lmax x popSize; each column is a chromosome c(m, tau_1, ..., tau_m, N+1, ...).
