vectorized lower_bound

[HelliceSaouli]

Hello I have 2 sorted vectors(a, b) and i would like to do some binary search for each element in b i would like to have a lower_bound from a. this is called vectorized binary search which is possible in thrust, but i can't find it in boost

Are you talking about this binary search

[HelliceSaouli]

yes, that one. I end up implementing my own brute force custom kernel for it. but it would be nice to have boost version
