Perhaps you should try some spelling variations:
"code in multiobjective design program" » "code in objective design program" (Expand search), "code _ multiobjective design program" (Expand search), "code using multiobjective design program" (Expand search), "code multi objective design program" (Expand search), "code in multiobjective design problem" (Expand search), "code and multiobjective design program" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa python python python programming" (Expand search), "manim python 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: "((\"code in multiobjective design program\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( code in multiobjective design program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("code in multiobjective design program") OR ("api python python python programming"))*.
