Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"modified passive quantization algorithmssss" » "modified adaptive quantization algorithmssss"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive quantization algorithmssss\") OR (\"modified objective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified passive quantization algorithmssss ) OR ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive quantization algorithmssss") OR ("modified objective optimisation algorithm"))*.
