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)
"coder modelling image coding program" » "cover modelling image coding program" (Expand search), "order modelling image coding program" (Expand search), "model modelling image coding program" (Expand search), "coder modelling climate coding program" (Expand search), "coder modelling case coding program" (Expand search), "coder modelling pages coding program" (Expand search), "coder modelling image cloning program" (Expand search), "coder modelling image loading program" (Expand search), "coder modelling image cooling programs" (Expand search), "coder modelling image reading program" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder modelling image coding program") OR ("and optimization python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder modelling image coding program\") OR (\"and optimization python python programming\"))".
• Removing quotes may allow a broader search: (( coder modelling image coding program ) OR ( and optimization python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder modelling image coding program") OR ("and optimization python python programming"))*.
