Perhaps you should try some spelling variations:
"modified changing optimization algorithmss" » "modified changing optimisation algorithm", "modified changing estimation algorithms", "modified changing estimation algorithm", "modified changing optimisation algorithms", "modified changing estimation algorithmss", "modified staffing optimization algorithmss", "modified caging optimization algorithmss"
"modified bayesian optimization algorithms" » "modified bayesian optimisation algorithm", "modified bayesian estimation algorithms", "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 algorithmss\") OR (\"modified bayesian optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified changing optimization algorithmss ) OR ( modified bayesian optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified changing optimization algorithmss") OR ("modified bayesian optimization algorithms"))*.
