Perhaps you should try some spelling variations:
"implement modeling algorithm" » "implement scheduling algorithm" (Expand Search), "implemented modeling algorithm" (Expand Search), "implementing modeling algorithm" (Expand Search)
"element ii algorithm" » "element rd algorithm" (Expand Search), "element _ algorithms" (Expand Search), "elements ii algorithm" (Expand Search)
"element network algorithm" » "elements network 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: (("implement modeling algorithm") OR ((("element ii algorithm") OR ("element network algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement modeling algorithm\") OR (((\"element ii algorithm\") OR (\"element network algorithm\"))))".
• Removing quotes may allow a broader search: (( implement modeling algorithm ) OR ((( element ii algorithm ) OR ( element network algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement modeling algorithm") OR ((("element ii algorithm") OR ("element network algorithm"))))*.
