Perhaps you should try some spelling variations:
"modified invasive optimization algorithmss" » "modified invasive optimisation algorithm", "modified invasive estimation algorithms", "modified invasive estimation algorithm", "modified invasive optimisation algorithms", "modified invasive estimation algorithmss", "modified passive optimization algorithmss"
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing optimization algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified invasive optimization algorithmss") OR ("modified static optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified invasive optimization algorithmss\") OR (\"modified static optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified invasive optimization algorithmss ) OR ( modified static optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive optimization algorithmss") OR ("modified static optimization algorithms"))*.
