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