Perhaps you should try some spelling variations:
"data modelling algorithm" » "data modeling algorithm" (Expand Search), "data processing algorithm" (Expand Search)
"elements network algorithm" » "elements new algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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: (("elements network algorithm") OR ((("data using algorithm") OR ("data modelling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements network algorithm\") OR (((\"data using algorithm\") OR (\"data modelling algorithm\"))))".
• Removing quotes may allow a broader search: (( elements network algorithm ) OR ((( data using algorithm ) OR ( data modelling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements network algorithm") OR ((("data using algorithm") OR ("data modelling algorithm"))))*.
