Keywords

Usage
nlrq.control(maxiter=100, k=2, InitialStepSize = 1, big=1e+20, eps=1e-07, beta=0.97)
Arguments
maxiter

maximum number of allowed iterations

k

the number of iterations of the Meketon algorithm to be calculated in each step, usually 2 is reasonable, occasionally it may be helpful to set k=1

InitialStepSize

Starting value in optim to determine the step length of iterations. The default value of 1 is sometimes too optimistic. In such cases, the value 0 forces optim to just barely stick its toe in the water.

big

a large scalar

eps

tolerance for convergence of the algorithm

beta

a shrinkage parameter which controls the recentering process in the interior point algorithm.
