Perhaps you should try some spelling variations:
"pregel selection algorithm" » "pregel detection algorithm" (Expand Search), "pregel detection algorithms" (Expand Search), "pregel prediction algorithms" (Expand Search), "prey selection algorithm" (Expand Search), "panel selection algorithm" (Expand Search), "careful selection algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"elements based algorithm" » "experiments based algorithm" (Expand Search), "elements related algorithm" (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: (("elements based algorithm") OR ((("pregel selection algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements based algorithm\") OR (((\"pregel selection algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements based algorithm ) OR ((( pregel selection algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements based algorithm") OR ((("pregel selection algorithm") OR ("neural coding algorithm"))))*.
