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)
"develop tree algorithms" » "develop three algorithms" (Expand Search), "develop art algorithms" (Expand Search), "develop two algorithms" (Expand Search), "develop new algorithms" (Expand Search), "develop targeted algorithms" (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: (("data modeling algorithm") OR ((("develop tree algorithms") OR ("settlement data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data modeling algorithm\") OR (((\"develop tree algorithms\") OR (\"settlement data algorithm\"))))".
• Removing quotes may allow a broader search: (( data modeling algorithm ) OR ((( develop tree algorithms ) OR ( settlement data algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data modeling algorithm") OR ((("develop tree algorithms") OR ("settlement data algorithm"))))*.
