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)
"basis function _ coding program" » "basis functions _ coding program" (Expand search), "basis function _ cloning program" (Expand search), "basis function _ loading program" (Expand search), "basis function _ 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: "((\"basis function _ coding program\") OR (\"and optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( basis function _ coding program ) OR ( and optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("basis function _ coding program") OR ("and optimization python python programming"))*.
