Perhaps you should try some spelling variations:
"using computation using linear programming" » "using computational using linear programming" (Expand search), "using imputation using linear programming" (Expand search), "using compilation using linear programming" (Expand search), "using computations using linear programming" (Expand search), "using computation in linear programming" (Expand search), "using composition using linear programming" (Expand search)
"using medium python python programming" » "using manim python python programming" (Expand search), "using medium pythons python programming" (Expand search), "using medium piton python programming" (Expand search), "using medium pitons python programming" (Expand search), "using sodium 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 using linear programming\") OR (\"using medium python python programming\"))~".
• Removing quotes may allow a broader search: (( using computation using linear programming ) OR ( using medium python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computation using linear programming") OR ("using medium python python programming"))*.
