Perhaps you should try some spelling variations:
"advanced populations using subsampling program" » "advanced computations using subsampling program" (Expand search), "adapted populations using subsampling program" (Expand search), "advanced modulation using subsampling program" (Expand search), "advanced populations using sampling program" (Expand search), "advanced formulations using subsampling program" (Expand search), "advanced populations and subsampling program" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ python python programming" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced populations using subsampling program\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced populations using subsampling program ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced populations using subsampling program") OR ("using in python python programming"))*.
