Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"modified market estimation algorithm" » "modified market optimization algorithm", "modified parameter estimation algorithm", "modified male estimation algorithm"

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