Perhaps you should try some spelling variations:
"modified static optimization algorithmss" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithms", "modified stage optimization algorithmss", "modified stochastic optimization algorithmss", "modified staffing optimization algorithmss"
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective solution algorithm", "modified objective convolution 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 static optimization algorithmss") or ("modified objective evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimization algorithmss") OR ("modified objective evolution algorithm")).
• Removing quotes may allow a broader search: (( modified static optimization algorithmss ) or ( modified objective evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimization algorithmss") or ("modified objective evolution algorithm"))*.
