Perhaps you should try some spelling variations:
"neural modeling algorithm" » "neural making algorithm" (Expand Search), "neural modelling algorithm" (Expand Search), "neural coding algorithm" (Expand Search), "causal modeling algorithm" (Expand Search)
"implement routine algorithm" » "implement routing algorithm" (Expand Search), "implement cosine algorithm" (Expand Search), "implement retinex algorithm" (Expand Search)
"element abs algorithm" » "element anbs algorithm" (Expand Search), "element pass algorithm" (Expand Search), "element b algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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: (("element abs algorithm") OR ((("implement routine algorithm") OR ("neural modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element abs algorithm\") OR (((\"implement routine algorithm\") OR (\"neural modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element abs algorithm ) OR ((( implement routine algorithm ) OR ( neural modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element abs algorithm") OR ((("implement routine algorithm") OR ("neural modeling algorithm"))))*.
