Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"modified made optimization algorithms" » "modified made estimation algorithms", "modified made estimation algorithm", "modified made optimized algorithms", "modified game optimization algorithms", "modified market optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms", "modified adam optimization algorithms", "modified df optimization algorithms"

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: (("modified multiobjective optimisation algorithm") OR ("modified made optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( modified made optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("modified made optimization algorithms"))*.
