Perhaps you should try some spelling variations:
"and computational using linear programing" » "and computation using linear programing" (Expand search), "and computations using linear programing" (Expand search), "and computacional usinas linear programing" (Expand search), "_ computational using linear programing" (Expand search), "and computational using linear programming" (Expand search), "and computational using linear programmin" (Expand search), "and computational using linear program" (Expand search)
"using modulo python python programming" » "using codigo python python programming" (Expand search), "using modulo pythons python programming" (Expand search), "using modulo piton python programming" (Expand search), "using modulo pitons python programming" (Expand search), "using module python python programming" (Expand search), "using model python python programming" (Expand search), "using models python 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 linear programing\") OR (\"using modulo python python programming\"))~".
• Removing quotes may allow a broader search: (( and computational using linear programing ) OR ( using modulo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational using linear programing") OR ("using modulo python python programming"))*.
