Perhaps you should try some spelling variations:
"and computational using subsampling program" » "and computation using subsampling program" (Expand search), "and computations using subsampling program" (Expand search), "and computacional usinas subsampling program" (Expand search), "and computational using sampling program" (Expand search), "_ computational using subsampling program" (Expand search), "and computational and subsampling program" (Expand search)
"using java code python programming" » "using java codigo python programming" (Expand search), "using java pacote 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: "((\"and computational using subsampling program\") OR (\"using java code python programming\"))~".
• Removing quotes may allow a broader search: (( and computational using subsampling program ) OR ( using java code python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational using subsampling program") OR ("using java code python programming"))*.
