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