Perhaps you should try some spelling variations:
"modified parameters optimized algorithms" » "modified parameters optimized algorithm", "modified parameters optimizer algorithms", "modified parameters optimization algorithms"
"modified invasive evolution algorithm" » "modified invasive solution algorithm", "modified invasive evolutionary algorithm", "modified invasive convolution algorithms", "modified invasive ventilation algorithm", "modified passive evolution algorithm"

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