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 static optimization algorithm" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization 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 static optimization algorithm") or ("modified invasive optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimization algorithm") OR ("modified invasive optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified static optimization algorithm ) or ( modified invasive optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithm") or ("modified invasive optimization algorithmss"))*.
