Perhaps you should try some spelling variations:
"advanced computational using simplex program" » "and computational using simplex program" (Expand search), "based computational using simplex program" (Expand search), "advanced computation using simplex program" (Expand search), "advanced computations using simplex program" (Expand search), "advanced computacional usinas simplex program" (Expand search), "advanced computational using simples program" (Expand search), "advanced computational using complex program" (Expand search), "advanced computational using simple program" (Expand search), "advanced computational using samples program" (Expand search)
"using modis pym python programming" » "using mobile pym python programming" (Expand search), "using modis pytm python programming" (Expand search), "using modis tm 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: "((\"advanced computational using simplex program\") OR (\"using modis pym python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computational using simplex program ) OR ( using modis pym python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computational using simplex program") OR ("using modis pym python programming"))*.
