Perhaps you should try some spelling variations:
"and optimization python python programming" » "and optimization method python programming" (Expand search), "and optimization option python programming" (Expand search), "and optimization methods python programming" (Expand search), "and optimization pythons python programming" (Expand search), "and optimization piton python programming" (Expand search), "and optimization pitons python programming" (Expand search)
"powder solution with sample program" » "powder production with sample program" (Expand search), "powder solution with simples program" (Expand search), "powder solution with simplex program" (Expand search), "powder solution with sampling program" (Expand search), "powder solutions with sample program" (Expand search), "powder solution with simple program" (Expand search), "powder solution with same program" (Expand search), "powder solution with examples 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: "((\"powder solution with sample program\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( powder solution with sample program ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("powder solution with sample program") OR ("and optimization python python programming"))*.
