Perhaps you should try some spelling variations:
"using computation and sampling program" » "using computational and sampling program" (Expand search), "using imputation and sampling program" (Expand search), "using compilation and sampling program" (Expand search), "using computation and labeling program" (Expand search), "using computation and smoking program" (Expand search), "using computation and jumping program" (Expand search), "using computation of sampling program" (Expand search), "using computation _ sampling program" (Expand search), "using computation and sample 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: "((\"using computation and sampling program\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation and sampling program ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation and sampling program") OR ("using in python python programming"))*.
