Perhaps you should try some spelling variations:
"modified changing optimization algorithmssss" » "modified changing optimization algorithms", "modified changing optimisation algorithm", "modified changing optimization algorithmsssss", "modified changing optimisation algorithmssss", "modified changing estimation algorithmssss", "modified staffing optimization algorithmssss", "modified caging optimization algorithmssss"
"modified bayesian optimization algorithm" » "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm", "modified bayesian estimation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified changing optimization algorithmssss\") OR (\"modified bayesian optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified changing optimization algorithmssss ) OR ( modified bayesian optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified changing optimization algorithmssss") OR ("modified bayesian optimization algorithm"))*.
