Perhaps you should try some spelling variations:
"wave propagation python python programming" » "wave propagation method python programming" (Expand search), "wave propagation path python programming" (Expand search), "wave programmation python python programming" (Expand search), "wave propagation pythons python programming" (Expand search), "wave propagation piton python programming" (Expand search), "wave propagation pitons python programming" (Expand search)
"coder and vector coding program" » "coder and vector cloning program" (Expand search), "coder and vector loading program" (Expand search), "coder and vector cooling programs" (Expand search), "code and vector coding program" (Expand search), "codes and vector coding program" (Expand search), "poder and vector coding 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 and vector coding program") OR ("wave propagation python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder and vector coding program\") OR (\"wave propagation python python programming\"))*".
• Removing quotes may allow a broader search: (( coder and vector coding program ) OR ( wave propagation python python programming ))*.
