Perhaps you should try some spelling variations:
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified invasive optimizer algorithmss" » "modified invasive optimizer algorithms", "modified invasive optimized algorithms", "modified invasive optimized algorithm", "modified passive optimizer algorithmss"

Try widening your search to All Fields.

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