Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"core learnings from algorithm" » "core learning from algorithm", "core weaning from algorithm", "core learnings mom algorithm", "core learnings adam algorithm", "more learnings from algorithm", "care learnings from algorithm"

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

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