Hello,

I am trying to apply the TOS algorithm from your paper https://arxiv.org/pdf/1804.02339.pdf by using the COPT implementation. There is one detail that I do not really catch here.

Based on your article, it seems to me that the steps (lines 2-7) in Algorithm 1 of https://arxiv.org/pdf/1804.02339.pdf do not match the implementation:

I might be wrong but shouldn't the line:

(

come after the loop begins:

(

so as to match the steps (lines 2-7) in Algorithm 1 of https://arxiv.org/pdf/1804.02339.pdf

As it is, it seems to me that the variable x is never updated during the backtracking. Am I missing something ?

Thank you for the fantastic work !
