A recursive quadratic programming method with active set strategy for optimal design
TL;DR: The algorithm of Pshenichny had been undiscovered until now, and is examined here for the first time, and it is found that the proof of global convergence by Han requires computing sensitivity coefficients (derivatives) of all constraint functions of the problem at every iteration, which is prohibitively expensive for large-scale applications in optimal design.
