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