Perhaps you should try some spelling variations:
formulations using » formulations in (Expand search), formulations and (Expand search)
ranking python » ranking method (Expand search), ranking position (Expand search)
parse program » purse program (Expand search), care program (Expand search), party program (Expand search)
using ranking » using stacking (Expand search), using resting (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
using parse » using coarse (Expand search), using pade (Expand search), using part (Expand search)

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

• Removing quotes may allow a broader search: (( AND formulations using parse program ) OR ( using ranking python python programming ))*.
