Perhaps you should try some spelling variations:
rate complexity » case complexity (Expand search), care complexity (Expand search), data complexity (Expand search)
sampling python » sampling method (Expand search), sampling position (Expand search), sampling methods (Expand search)
using sampling » using subsampling (Expand search), using saline (Expand search), using samples (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
coder rate » cover rate (Expand search), power rate (Expand search), code rape (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( coder rate complexity control program ) OR ( using sampling python python programming ))~.
