Perhaps you should try some spelling variations:
"modified adaptive construction algorithms" » "modified adaptive convolution algorithms", "modified passive construction algorithms"
"modified quantile optimization algorithms" » "modified quantile optimisation algorithm", "modified quantile estimation algorithms", "modified quantile estimation algorithm", "modified quadratic optimization algorithms", "modified static 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 adaptive construction algorithms"))~.
• Removing quotes may allow a broader search: (( modified quantile optimization algorithms ) or ( modified adaptive construction algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quantile optimization algorithms") or ("modified adaptive construction algorithms"))*.
