Perhaps you should try some spelling variations:
"present modeling algorithm" » "present scheduling algorithm" (Expand Search), "event modeling algorithm" (Expand Search), "agent modeling algorithm" (Expand Search)
"element cosine algorithm" » "elements cosine algorithm" (Expand Search)
"neural colony algorithm" » "neural colon 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 cosine algorithm") OR ((("present modeling algorithm") OR ("neural colony algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element cosine algorithm\") OR (((\"present modeling algorithm\") OR (\"neural colony algorithm\"))))".
• Removing quotes may allow a broader search: (( element cosine algorithm ) OR ((( present modeling algorithm ) OR ( neural colony algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element cosine algorithm") OR ((("present modeling algorithm") OR ("neural colony algorithm"))))*.
