Perhaps you should try some spelling variations:
"implement modeling algorithm" » "implement scheduling algorithm" (Expand Search), "implemented modeling algorithm" (Expand Search), "implementing modeling algorithm" (Expand Search)
"data using algorithms" » "data cosine algorithm" (Expand Search)
"element data algorithms" » "element jaya algorithm" (Expand Search), "elements data algorithms" (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: (((("implement modeling algorithm") OR ("element data algorithms"))) OR ("data using algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement modeling algorithm\") OR (\"element data algorithms\"))) OR (\"data using algorithms\"))".
• Removing quotes may allow a broader search: (((( implement modeling algorithm ) OR ( element data algorithms ))) OR ( data using algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("implement modeling algorithm") OR ("element data algorithms"))) OR ("data using algorithms"))*.
