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"
"mapping weaning from algorithm" » "mapping learning from algorithm", "mapping weaning mom algorithm", "mapping weaning adam algorithm", "mapping reading from algorithm", "mapping learnings from algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping weaning from algorithm") OR ("modified objective optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping weaning from algorithm\") OR (\"modified objective optimization algorithm\"))".
• Removing quotes may allow a broader search: (( mapping weaning from algorithm ) OR ( modified objective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mapping weaning from algorithm") OR ("modified objective optimization algorithm"))*.
