init_pos does not seem to work as expected

[dkgupta90]

HI @ljvmiranda921 ,
Thank you making this toolkit available publicly. I am trying to work with the init_pos argument but it does not seem to work as expected. My init_pos matrix has a size of (697, 9). When I pass it, I expect the objective value to be same at iteration 1 if I run the code many times. However, the best objective value that I get after iteration 1 differs across multiple runs. Could you please let me know in case I am missing something in the working here?
