Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified a optimization algorithms" » "modified a optimisation algorithm", "modified a estimation algorithms", "modified a optimized algorithms", "modified _ optimization algorithms", "modified _ optimisation algorithms", "modified game optimization algorithms", "modified df optimization algorithms", "modified adam optimization algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective estimation algorithm") or ("modified a optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective estimation algorithm") OR ("modified a optimization algorithms")).
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithm ) or ( modified a optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithm") or ("modified a optimization algorithms"))*.
