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)
"systems using algorithm" » "systems using algorithms" (Expand Search), "systems routing algorithm" (Expand Search), "systems fusion algorithm" (Expand Search), "system using algorithm" (Expand Search), "systems user algorithm" (Expand Search)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement atlas 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: (("settlement data algorithm") OR ((("data modeling algorithm") OR ("systems using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"settlement data algorithm\") OR (((\"data modeling algorithm\") OR (\"systems using algorithm\"))))".
• Removing quotes may allow a broader search: (( settlement data algorithm ) OR ((( data modeling algorithm ) OR ( systems using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("settlement data algorithm") OR ((("data modeling algorithm") OR ("systems using algorithm"))))*.
