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