Perhaps you should try some spelling variations:
"tables algorithms" » "tableau algorithms", "tableau algorithm", "types algorithms"
"trees algorithms" » "tree algorithm", "access algorithms", "treatment algorithms"
"tree algorithms" » "tree algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("tables algorithms") OR ((("trees algorithms") OR ("tree algorithms")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tables algorithms\") or (((\"trees algorithms\") OR (\"tree algorithms\"))))".
• Removing quotes may allow a broader search: (( tables algorithms ) or ((( trees algorithms ) OR ( tree algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("tables algorithms") or ((("trees algorithms") OR ("tree algorithms"))))*.
