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

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