Perhaps you should try some spelling variations:
"event modeling algorithm" » "event scheduling algorithm" (Expand Search), "agent modeling algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"tested using algorithm" » "tested cosine algorithm" (Expand Search), "system using algorithm" (Expand Search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("element method algorithm") OR ((("tested using algorithm") OR ("event modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"tested using algorithm\") OR (\"event modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( tested using algorithm ) OR ( event modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("tested using algorithm") OR ("event modeling algorithm"))))*.
