comment Why does [dz(t)]^2 converge to dt over infinitesimally short time periods?
"Use one instead of other because both are small" . This is not the reason unfortunately

comment Sampling problem in portfolio optimization
Updated the questions . No of bonds are 1000. (not 1000k) . I have already done the filtering you mentioned in A . if we reduce it to 10 bonds even then I want to sample either 1,2,..all 10 bonds such as the constraints and objective is satisfied. Thus I can reduce my problem size but I am stuck with best sampling process to avoid brute force all combinations.
