Perhaps you should try some spelling variations:
"lu factorization using python programming" » "lu vectorization using python programming" (Expand search), "lu valorization using python programming" (Expand search), "lu atomization using python programming" (Expand search), "lu factorization usando python programming" (Expand search), "lu factorization in python programming" (Expand search)
"coder solution in coding program" » "code solution in coding program" (Expand search), "powder solution in coding program" (Expand search), "copper solution in coding program" (Expand search), "coder solution in cloning program" (Expand search), "coder solution in loading program" (Expand search), "coder solution in cooling programs" (Expand search), "coder solutions in coding program" (Expand search), "coder solution and coding program" (Expand search), "coder solution _ coding program" (Expand search), "coder solution on coding program" (Expand search), "coder solution in decoding program" (Expand search), "coder solution non 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 solution in coding program") OR ("lu factorization using python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder solution in coding program\") OR (\"lu factorization using python programming\"))*".
• Removing quotes may allow a broader search: (( coder solution in coding program ) OR ( lu factorization using python programming ))*.
