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