Confusion about beta_multiplier function in the dogleg implementation. #29

Open HaiyongJiang opened 5 years ago

Dear @mattloper , thank you for your work on the chumpy and the dogleg implementation. I have some questions about function beta_multiplier in optimization_interal.py in line#268. According to my understanding, \beta should satisfy "||d_sd + \beta*(d_gn-d_sd)||_2 == delta", but \beta is not calculated by solving the equation. Can you give me some hints about your calculation of \beta? Thank you.
