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 quantile optimization algorithms" » "modified quantile optimisation algorithm", "modified quantile estimation algorithms", "modified quantile estimation algorithm", "modified quadratic optimization algorithms", "modified static optimization algorithms", "modified adaptive optimization algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quantile optimization algorithms") OR ("modified objective estimation algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified quantile optimization algorithms ) or ( modified objective estimation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quantile optimization algorithms") or ("modified objective estimation algorithmssss"))*.
