Perhaps you should try some spelling variations:
"settlement update algorithm" » "settlement data algorithm" (Expand Search), "settlement under algorithm" (Expand Search), "settlement pass algorithm" (Expand Search), "settlement data algorithms" (Expand Search), "settlement ipca algorithm" (Expand Search)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"elements cscap algorithm" » "elements cc3d algorithm" (Expand Search), "elements ipca algorithm" (Expand Search), "elements custom algorithm" (Expand Search), "elements crcy 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 update algorithm") OR ("elements cscap algorithm"))) OR ("level coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"settlement update algorithm\") OR (\"elements cscap algorithm\"))) OR (\"level coding algorithm\"))".
• Removing quotes may allow a broader search: (((( settlement update algorithm ) OR ( elements cscap algorithm ))) OR ( level coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("settlement update algorithm") OR ("elements cscap algorithm"))) OR ("level coding algorithm"))*.
