Perhaps you should try some spelling variations:
"coder arduino system algorithm application" » "coder arduino system algorithm optimization" (Expand search), "coder arduino system algorithm selection" (Expand search), "coder arduino based algorithm application" (Expand search), "coder arduino swarm algorithm application" (Expand search), "con arduino system algorithm application" (Expand search), "ide arduino system algorithm application" (Expand search), "solar arduino system algorithm application" (Expand search)
"on python python python programming" » "on pythons python python programming" (Expand search), "on piton python python programming" (Expand search), "on pitons python python programming" (Expand search), "in python pythin python programming" (Expand search), "of python pythof python programming" (Expand search), "_ python pyth_ python programming" (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 arduino system algorithm application") OR ("on python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder arduino system algorithm application\") OR (\"on python python python programming\"))".
• Removing quotes may allow a broader search: (( coder arduino system algorithm application ) OR ( on python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder arduino system algorithm application") OR ("on python python python programming"))*.
