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