Perhaps you should try some spelling variations:
"element scraping algorithm" » "element sampling algorithm" (Expand Search), "element tracking algorithm" (Expand Search), "element making algorithm" (Expand Search), "element strain algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"element rl algorithm" » "element rl algorithms" (Expand Search), "element rf algorithm" (Expand Search), "element ml algorithms" (Expand Search), "element ree algorithm" (Expand Search), "element ore algorithm" (Expand Search), "element _ algorithm" (Expand Search)
"element four algorithms" » "element group algorithms" (Expand Search), "element ore algorithms" (Expand Search), "element fbe algorithms" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("element scraping algorithm") OR ((("element rl algorithm") OR ("element four algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element scraping algorithm\") OR (((\"element rl algorithm\") OR (\"element four algorithms\"))))".
• Removing quotes may allow a broader search: (( element scraping algorithm ) OR ((( element rl algorithm ) OR ( element four algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("element scraping algorithm") OR ((("element rl algorithm") OR ("element four algorithms"))))*.
