Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"enabling learning convolution algorithms" » "enabling learning evolution algorithm", "enabling learning solution algorithm", "mapping learning convolution 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 objective optimization algorithm") or ("enabling learning convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimization algorithm") OR ("enabling learning convolution algorithms"))*.
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) or ( enabling learning convolution algorithms ))*.
