Perhaps you should try some spelling variations:
"modified changing estimation algorithmssss" » "modified changing estimation algorithms", "modified channel estimation algorithmssss", "modified charging station algorithmssss", "modified caging estimation algorithmssss"
"modified bayesian estimation algorithm" » "modified bayesian optimization algorithm"

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