Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"active learning convolution algorithm" » "active learning convolution algorithms", "active learning evolution algorithm", "active learning solution algorithm", "machine learning convolution algorithm"

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

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