Perhaps you should try some spelling variations:
"modified invasive optimization algorithms" » "modified invasive optimisation algorithm", "modified invasive estimation algorithms", "modified invasive estimation algorithm", "modified passive optimization algorithms"
"modified parameter optimized algorithms" » "modified parameter optimized algorithm", "modified parameter optimizer algorithms", "modified parameter 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 algorithms") or ("modified parameter optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive optimization algorithms") OR ("modified parameter optimized algorithms"))*.
• Removing quotes may allow a broader search: (( modified invasive optimization algorithms ) or ( modified parameter optimized algorithms ))*.
