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 caging optimization algorithms" » "modified caging optimisation algorithm", "modified caging estimation algorithms", "modified caging estimation algorithm", "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 caging optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified invasive optimization algorithmss\") OR (\"modified caging optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified invasive optimization algorithmss ) OR ( modified caging optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive optimization algorithmss") OR ("modified caging optimization algorithms"))*.
