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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learnings from algorithm\") OR (\"modified multiobjective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( mapping learnings from algorithm ) OR ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("mapping learnings from algorithm") OR ("modified multiobjective optimization algorithm"))*.
