Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"elements based algorithms" » "elements based algorithm" (Expand Search), "experiments based algorithms" (Expand Search), "elements related algorithms" (Expand Search)
"recent study algorithm" » "recent wsindy algorithm" (Expand Search), "recent td3 algorithm" (Expand Search), "recent seu algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent studies 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: (("data modeling algorithm") OR ((("recent study algorithm") OR ("elements based algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"recent study algorithm\") OR (\"elements based algorithms\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( recent study algorithm ) OR ( elements based algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("recent study algorithm") OR ("elements based algorithms"))))*.
