triqs.utility.dichotomy

Dichotomy / regula-falsi solver for \(y = f(x)\).

Provides dichotomy(), a one-dimensional root finder that brackets a sign change by stepping outward from an initial guess and then refines the root using a linear-interpolation (regula-falsi) update rather than plain bisection. Progress is reported through triqs.utility.mpi, so the solver is safe to call from MPI runs.

Functions

dichotomy(function, x_init, y_value, ...[, ...])

Find \(x\) such that \(f(x) = y_{\mathrm{value}}\).
