The simplest way to solve data integrity and state synchronization between multiple threads is to lock them up. So with the Gil this super lock, and when more and more co

It can be eliminated once and then co-linearity is verified. If the member is removed before the co-linearity test, until there is no common linear variable. At the same time, it is best to avoid common linear variables in the final model. Of course, here
