Perhaps you should try some spelling variations:
"scale optimization python python programming" » "scale optimization method python programming" (Expand search), "scale optimization option python programming" (Expand search), "scale optimization methods python programming" (Expand search), "shape optimization python python programming" (Expand search), "whale optimization python python programming" (Expand search), "angle optimization python python programming" (Expand search), "scale optimization pythons python programming" (Expand search), "scale optimization piton python programming" (Expand search), "scale optimization pitons python programming" (Expand search)
"coder convention and coding program" » "model convention and coding program" (Expand search), "code conventions and coding program" (Expand search), "code conventional and coding program" (Expand search), "coder conventional and coding program" (Expand search), "coder convention on coding program" (Expand search), "coder conversion and coding program" (Expand search), "coder convention and cloning program" (Expand search), "coder convention and loading program" (Expand search), "coder convention and cooling programs" (Expand search), "coder convention and coping program" (Expand search), "coder convention and cooling program" (Expand search), "coder convention and 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 convention and coding program\") OR (\"scale optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder convention and coding program ) OR ( scale optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder convention and coding program") OR ("scale optimization python python programming"))*.
