Perhaps you should try some spelling variations:
"present modeling algorithm" » "present making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "present model algorithm" (Expand Search), "patient modeling algorithm" (Expand Search)
"neural codingnb algorithm" » "neural cosine algorithm" (Expand Search), "neural coding algorithm" (Expand Search)
"element dbo algorithm" » "element modbo algorithm" (Expand Search), "element pso algorithm" (Expand Search), "element box algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element data 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 dbo algorithm") OR ((("present modeling algorithm") OR ("neural codingnb algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element dbo algorithm\") OR (((\"present modeling algorithm\") OR (\"neural codingnb algorithm\"))))".
• Removing quotes may allow a broader search: (( element dbo algorithm ) OR ((( present modeling algorithm ) OR ( neural codingnb algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element dbo algorithm") OR ((("present modeling algorithm") OR ("neural codingnb algorithm"))))*.
