Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified changing optimized algorithm" » "modified changing optimized algorithms", "modified changing optimizer algorithms", "modified choosing optimizer algorithm", "modified caging optimized algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified changing optimized algorithm") or ("modified objective convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified changing optimized algorithm") OR ("modified objective convolution algorithms"))*.
• Removing quotes may allow a broader search: (( modified changing optimized algorithm ) or ( modified objective convolution algorithms ))*.
