Perhaps you should try some spelling variations:
"modified adaptive optimization algorithmsss" » "modified adaptive optimization algorithms", "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified objective optimization algorithmsss", "modified adaptive quantization algorithmsss", "modified static optimization algorithmsss", "modified passive optimization algorithmsss"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

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: (("modified objective allocation algorithm") or ("modified adaptive optimization algorithmsss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective allocation algorithm") OR ("modified adaptive optimization algorithmsss")).
• Removing quotes may allow a broader search: (( modified objective allocation algorithm ) or ( modified adaptive optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective allocation algorithm") or ("modified adaptive optimization algorithmsss"))*.
