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