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

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