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)
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"level using algorithm" » "level using algorithms" (Expand Search), "level routing algorithm" (Expand Search), "level fusion algorithm" (Expand Search), "levels using 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: (("level using algorithm") OR ((("element mapping algorithm") OR ("neural modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"level using algorithm\") OR (((\"element mapping algorithm\") OR (\"neural modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( level using algorithm ) OR ((( element mapping algorithm ) OR ( neural modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("level using algorithm") OR ((("element mapping algorithm") OR ("neural modeling algorithm"))))*.
