Perhaps you should try some spelling variations:
"effects modeling algorithm" » "effects making algorithm" (Expand Search), "effects model algorithm" (Expand Search), "effects models algorithm" (Expand Search), "effect model algorithm" (Expand Search)
"effects using algorithm" » "effects using algorithms" (Expand Search), "effects routing algorithm" (Expand Search), "effects fusion algorithm" (Expand Search), "events using algorithm" (Expand Search)
"element tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element study 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: (("element tide algorithm") OR ((("effects using algorithm") OR ("effects modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tide algorithm\") OR (((\"effects using algorithm\") OR (\"effects modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( element tide algorithm ) OR ((( effects using algorithm ) OR ( effects modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element tide algorithm") OR ((("effects using algorithm") OR ("effects modeling algorithm"))))*.
