Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified deep evolutionary algorithm" » "modified deep evolution algorithm", "modified deep solution algorithm", "modified delphi evolutionary algorithm", "modified df evolutionary algorithm", "modified near evolutionary algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified deep evolutionary algorithm") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified deep evolutionary algorithm") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( modified deep evolutionary algorithm ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified deep evolutionary algorithm") or ("modified notion optimization algorithms"))*.
