Perhaps you should try some spelling variations:
"spatial modeling algorithm" » "spatial making algorithm" (Expand Search)
"element mesh algorithms" » "element best algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element best algorithm" (Expand Search), "element method algorithms" (Expand Search), "elements mges algorithms" (Expand Search), "element te algorithms" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (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: (("spatial modeling algorithm") OR ((("element mesh algorithms") OR ("element tree algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"spatial modeling algorithm\") OR (((\"element mesh algorithms\") OR (\"element tree algorithms\"))))".
• Removing quotes may allow a broader search: (( spatial modeling algorithm ) OR ((( element mesh algorithms ) OR ( element tree algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("spatial modeling algorithm") OR ((("element mesh algorithms") OR ("element tree algorithms"))))*.
