Perhaps you should try some spelling variations:
"modified seird optimization algorithms" » "modified seird estimation algorithms", "modified seird estimation algorithm", "modified seird optimized algorithms", "modified stage optimization algorithms", "modified network optimization algorithms", "modified near optimization algorithms"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective estimation algorithm", "modified objective estimation 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 objective optimisation algorithm") or ("modified seird optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimisation algorithm") OR ("modified seird optimization algorithms")).
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( modified seird optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("modified seird optimization algorithms"))*.
