Perhaps you should try some spelling variations:
"variance optimization method python programming" » "surface optimization method python programming" (Expand search), "engine optimization method python programming" (Expand search), "value optimization method python programming" (Expand search), "variance optimization methods python programming" (Expand search), "variance optimization method method programming" (Expand search), "variance optimization python python programming" (Expand search)
"coder solutions from coding program" » "coder solution from coding program" (Expand search), "holder solutions from coding program" (Expand search), "powder solutions from coding program" (Expand search), "coder solutions from cloning program" (Expand search), "coder solutions from loading program" (Expand search), "coder solutions from cooling programs" (Expand search), "coder solutions from decoding program" (Expand search), "coder solutions from cooking program" (Expand search), "coder solutions from codium 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 solutions from coding program\") OR (\"variance optimization method python programming\"))~".
• Removing quotes may allow a broader search: (( coder solutions from coding program ) OR ( variance optimization method python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder solutions from coding program") OR ("variance optimization method python programming"))*.
