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