Perhaps you should try some spelling variations:
"and optimization methods python programming" » "and optimization model python programming" (Expand search), "and optimization methods action programming" (Expand search), "and optimization pythons python programming" (Expand search), "and optimization methods method programming" (Expand search)
"coder solution using coding program" » "code solution using coding program" (Expand search), "copper solution using coding program" (Expand search), "powder solution using coding program" (Expand search), "coder solution using cloning program" (Expand search), "coder solution using loading program" (Expand search), "coder solution using cooling programs" (Expand search), "coder solution using coping program" (Expand search), "coder solution using coating program" (Expand search), "coder solution using cooking program" (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: "((\"coder solution using coding program\") OR (\"and optimization methods python programming\"))~".
• Removing quotes may allow a broader search: (( coder solution using coding program ) OR ( and optimization methods python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder solution using coding program") OR ("and optimization methods python programming"))*.
