Description: Uses a modification of Powell's method to find the minimum of a function of N variables Inputs: func -- the Python function or method to be minimized. x0 -- the initial guess. args -- extra arguments for func. callback -- an optional user-supplied function to call after each iteration. It is called as callback(xk), where xk is the current parameter vector. Outputs: (xopt, {fopt, xi, direc, iter, funcalls, warnflag}, {allvecs}) xopt -- minimizer of function fopt -- value of function at minimum: fopt = func(xopt) direc -- current direction set iter -- number of iterations funcalls -- number of function calls warnflag -- Integer warning flag: 1 : 'Maximum number of function evaluations.' 2 : 'Maximum number of iterations.' allvecs -- a list of solutions at each iteration Additional Inputs: xtol -- line-search error tolerance. ftol -- acceptable relative error in func(xopt) for convergence. maxiter -- the maximum number of iterations to perform. maxfun -- the maximum number of function evaluations. full_output -- non-zero if fval and warnflag outputs are desired. disp -- non-zero to print convergence messages. retall -- non-zero to return a list of the solution at each iteration See also: fmin, fmin_powell, fmin_cg, fmin_bfgs, fmin_ncg -- multivariate local optimizers leastsq -- nonlinear least squares minimizer fmin_l_bfgs_b, fmin_tnc, fmin_cobyla -- constrained multivariate optimizers anneal, brute -- global optimizers fminbound, brent, golden, bracket -- local scalar minimizers fsolve -- n-dimenstional root-finding brentq, brenth, ridder, bisect, newton -- one-dimensional root-finding fixed_point -- scalar fixed-point finder """ # we need to use a mutable object here that we can update in the # wrapper function fcalls, func = wrap_function(func, args) x = asarray(x0) if retall: allvecs = [x] N = len(x) rank = len(x.shape) if not -1 < rank < 2: raise ValueError, "Initial guess must be a scalar or rank-1 sequence." if maxiter is None: maxiter = N * 1000 if maxfun is None: maxfun = N * 1000 if direc is None: direc = eye(N, dtype=float) else: direc = asarray(direc, dtype=float) fval = squeeze(func(x)) x1 = x.copy() iter = 0; ilist = range(N) while True: fx = fval bigind = 0 delta = 0.0 for i in ilist: direc1 = direc[i] fx2 = fval fval, x, direc1 = _linesearch_powell(func, x, direc1, tol=xtol*100) if (fx2 - fval) > delta: delta = fx2 - fval bigind = i iter += 1 if callback is not None: callback(x) if retall: allvecs.append(x) if (2.0*(fx - fval) <= ftol*(abs(fx)+abs(fval))+1e-20): break if fcalls[0] >= maxfun: break if iter >= maxiter: break # Construct the extrapolated point direc1 = x - x1 x2 = 2*x - x1 x1 = x.copy() fx2 = squeeze(func(x2)) if (fx > fx2): t = 2.0*(fx+fx2-2.0*fval) temp = (fx-fval-delta) t *= temp*temp temp = fx-fx2 t -= delta*temp*temp if t < 0.0: fval, x, direc1 = _linesearch_powell(func, x, direc1, tol=xtol*100) direc[bigind] = direc[-1] direc[-1] = direc1 warnflag = 0 if fcalls[0] >= maxfun: warnflag = 1 if disp: print "Warning: Maximum number of function evaluations has "\ "been exceeded." elif iter >= maxiter: warnflag = 2 if disp: print "Warning: Maximum number of iterations has been exceeded" else: if disp: print "Optimization terminated successfully." print " Current function value: %f" % fval print " Iterations: %d" % iter print " Function evaluations: %d" % fcalls[0] x = squeeze(x) if full_output: retlist = x, fval, direc, iter, fcalls[0], warnflag if retall: retlist += (allvecs,) else: retlist = x if retall: retlist = (x, allvecs) return retlist | 62 |
