Re: [ompl-users] About the nearest neighbor data structure

[Mark M. <mm...@ri...>]

Hi Shupeng,

All of them are exact except for ompl::NearestNeighborsSqrtApprox, which is approximate (but doesn’t give approximation guarantees). You can use the ompl::NearestNeighborsFLANN wrapper interface to experiment with various other nn data structures from the FLANN library.

Best,

Mark
