Perhaps you should try some spelling variations:
"using computation using sampling program" » "using computational using sampling program" (Expand search), "using imputation using sampling program" (Expand search), "using compilation using sampling program" (Expand search), "using computations using sampling program" (Expand search), "using computation in sampling program" (Expand search), "using composition using sampling program" (Expand search), "using computation using labeling program" (Expand search), "using computation using smoking program" (Expand search), "using computation using jumping program" (Expand search), "using computation using subsampling program" (Expand search), "using computation using saline program" (Expand search), "using computation using samples program" (Expand search)
"using amide from python programming" » "using amine from python programming" (Expand search), "using amines from python programming" (Expand search), "using acid from python programming" (Expand search), "using amide from pathogen programming" (Expand search), "using amide from anthony programming" (Expand search), "using amides from python programming" (Expand search), "using amidase from python programming" (Expand search), "using made from 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 using sampling program\") OR (\"using amide from python programming\"))~".
• Removing quotes may allow a broader search: (( using computation using sampling program ) OR ( using amide from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation using sampling program") OR ("using amide from python programming"))*.
