Perhaps you should try some spelling variations:
"advanced computation using simplex program" » "advanced computations using simplex program" (Expand search), "advanced computational using simplex program" (Expand search), "advance computational using simplex program" (Expand search), "advanced computation in simplex program" (Expand search), "advanced composition using simplex program" (Expand search), "advanced computation using simples program" (Expand search), "advanced computation using complex program" (Expand search), "advanced computation using simple program" (Expand search), "advanced computation using samples program" (Expand search)
"using java and python programming" » "using java in python programming" (Expand search), "using java on python programming" (Expand search), "using java api python programming" (Expand search), "using java card python programming" (Expand search), "using java 3d 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 computation using simplex program\") OR (\"using java and python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computation using simplex program ) OR ( using java and python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computation using simplex program") OR ("using java and python programming"))*.
