What is sequential least SQuares programming Slsqp?

Sequential Least SQuares Programming optimizer. SLSQP minimizes a function of several variables with any combination of bounds, equality and inequality constraints. The method wraps the SLSQP Optimization subroutine originally implemented by Dieter Kraft.

What is key advantage in sequential quadratic programming method?

An advantage of these methods is that the active set from the previous iteration of the SQP algorithm is often a good estimate of the active set at the current iteration.

What is irls statistics?

IRLS is used to find the maximum likelihood estimates of a generalized linear model, and in robust regression to find an M-estimator, as a way of mitigating the influence of outliers in an otherwise normally-distributed data set. For example, by minimizing the least absolute errors rather than the least square errors.
