Perhaps you should try some spelling variations:
"modified invasive optimization algorithmss" » "modified invasive optimization algorithms", "modified invasive optimisation algorithm", "modified invasive estimation algorithms", "modified invasive optimization algorithmsss", "modified invasive optimisation algorithmss", "modified invasive estimation algorithmss", "modified passive optimization algorithmss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation 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 objective optimization algorithm") or ("modified invasive optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimization algorithm") OR ("modified invasive optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) or ( modified invasive optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") or ("modified invasive optimization algorithmss"))*.
