Perhaps you should try some spelling variations:
"based compilation using linear programming" » "based combination using linear programming" (Expand search), "based computation using linear programming" (Expand search), "based compensation using linear programming" (Expand search), "based completion using linear programming" (Expand search)
"using codigo python python programming" » "using codigo pythons python programming" (Expand search), "using codigo piton python programming" (Expand search), "using codigo pitons python programming" (Expand search), "using indigo python python programming" (Expand search), "using coding python python programming" (Expand search), "using codium 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: "((\"based compilation using linear programming\") OR (\"using codigo python python programming\"))~".
• Removing quotes may allow a broader search: (( based compilation using linear programming ) OR ( using codigo python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based compilation using linear programming") OR ("using codigo python python programming"))*.
