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