Perhaps you should try some spelling variations:
"current modeling algorithm" » "current making algorithm" (Expand Search), "current model algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "current smoking algorithm" (Expand Search)
"elements cscap algorithm" » "elements cc3d algorithm" (Expand Search), "elements ipca algorithm" (Expand Search), "elements custom algorithm" (Expand Search), "elements crcy algorithm" (Expand Search)
"present study algorithm" » "present wsindy algorithm" (Expand Search), "present td3 algorithm" (Expand Search), "present seu 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 cscap algorithm") OR ("present study algorithm"))) OR ("current modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements cscap algorithm\") OR (\"present study algorithm\"))) OR (\"current modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements cscap algorithm ) OR ( present study algorithm ))) OR ( current modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements cscap algorithm") OR ("present study algorithm"))) OR ("current modeling algorithm"))*.
