Package jline.api.da

Class Da_fpi

java.lang.Object

jline.api.da.Da_fpi

public final class Da_fpi
extends Object

Generic damped successive-substitution driver for decomposition-aggregation (DA) fixed-point iterations. Each call to the sweep performs one DA pass: solve the isolated submodels given the current coupling iterate x, exchange flows or rates, and return the updated iterate together with the comparison baseline for the convergence test. Mirrors matlab/src/api/da/da_fpi.m.
