Perhaps you should try some spelling variations:
"using computation in linear programming" » "using computational in linear programming" (Expand search), "using imputation in linear programming" (Expand search), "using compilation in linear programming" (Expand search), "using computation and linear programming" (Expand search), "using computation of linear programming" (Expand search), "using computation non linear programming" (Expand search), "using computation in line programming" (Expand search)
"using opencv python python programming" » "using opencv pythons python programming" (Expand search), "using opencv piton python programming" (Expand search), "using opencv pitons python programming" (Expand search), "using opencl python python programming" (Expand search), "using open python python programming" (Expand search), "usando opencv 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: "((\"using computation in linear programming\") OR (\"using opencv python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation in linear programming ) OR ( using opencv python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation in linear programming") OR ("using opencv python python programming"))*.
