Perhaps you should try some spelling variations:
"based computational using simplex program" » "and computational using simplex program" (Expand search), "by computational using simplex program" (Expand search), "based computation using simplex program" (Expand search), "based computations using simplex program" (Expand search), "based computacional usinas simplex program" (Expand search), "based computational using simples program" (Expand search), "based computational using complex program" (Expand search), "based computational using simple program" (Expand search), "based computational using samples program" (Expand search)
"using codes from python programming" » "using code from python programming" (Expand search), "using anodes from python programming" (Expand search), "using cone from python programming" (Expand search), "using codes from pathogen programming" (Expand search), "using codes from anthony programming" (Expand search), "using cestodes 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: "((\"based computational using simplex program\") OR (\"using codes from python programming\"))~".
• Removing quotes may allow a broader search: (( based computational using simplex program ) OR ( using codes from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational using simplex program") OR ("using codes from python programming"))*.
