Options for the DIRECT algorithm
Fields§
§max_fevals: usizeMaximum number of function evaluations
max_iterations: usizeMaximum number of iterations (subdivisions)
ftol_abs: f64Minimum function value improvement to continue (absolute tolerance)
ftol_rel: f64Relative tolerance on function value
vol_tol: f64Minimum rectangle size (stops when rectangles become too small)
epsilon: f64Epsilon parameter for selecting potentially optimal rectangles. Larger values bias toward global search; smaller toward local refinement. Jones (1993) recommends 1e-4 as a good default.
locally_biased: boolWhether to use the locally-biased variant (DIRECT-L, Gablonsky & Kelley 2001)
