Perhaps you should try some spelling variations:
"data modelling algorithm" » "data modeling algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"solved using algorithms" » "solved pacing algorithms" (Expand Search), "solved nine algorithms" (Expand Search), "solved sorting algorithms" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both 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: (((("data modelling algorithm") OR ("solved using algorithms"))) OR ("relevant data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data modelling algorithm\") OR (\"solved using algorithms\"))) OR (\"relevant data algorithms\"))".
• Removing quotes may allow a broader search: (((( data modelling algorithm ) OR ( solved using algorithms ))) OR ( relevant data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("data modelling algorithm") OR ("solved using algorithms"))) OR ("relevant data algorithms"))*.
