Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimized algorithms"
"modified made optimisation algorithm" » "modified made estimation algorithm", "modified made estimation algorithms", "modified game optimization algorithm", "modified market optimization algorithm", "modified stage optimization algorithm", "modified male optimisation algorithm", "modified adam optimisation algorithm", "modified df optimisation 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: "((\"modified made optimisation algorithm\") OR (\"modified multiobjective optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified made optimisation algorithm ) OR ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified made optimisation algorithm") OR ("modified multiobjective optimization algorithms"))*.
