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