Perhaps you should try some spelling variations:
"data modeling algorithm" » "data making algorithm" (Expand Search), "data modelling algorithm" (Expand Search), "data models algorithm" (Expand Search)
"element network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"based mapping algorithm" » "based making algorithm" (Expand Search), "based mining algorithm" (Expand Search), "based learning algorithm" (Expand Search), "based machine 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 network algorithm") OR ((("data modeling algorithm") OR ("based mapping algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element network algorithm\") OR (((\"data modeling algorithm\") OR (\"based mapping algorithm\"))))".
• Removing quotes may allow a broader search: (( element network algorithm ) OR ((( data modeling algorithm ) OR ( based mapping algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element network algorithm") OR ((("data modeling algorithm") OR ("based mapping algorithm"))))*.
