Perhaps you should try some spelling variations:
"and computation using linear programming" » "and computations using linear programming" (Expand search), "and computation in linear programming" (Expand search), "and composition using linear programming" (Expand search), "and computational using linear programming" (Expand search), "of computation using linear programming" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking 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 computation using linear programming\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation using linear programming ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation using linear programming") OR ("using coding python python programming"))*.
