Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
quantile optimization » quantile estimation, quadratic optimization, static optimization
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified positive » modified passive, modified adaptive
positive solution » positive solutions
modified quantile » modified adaptive

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified positive solution algorithm ) or ( modified quantile optimization algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified positive solution algorithm ) OR ( modified quantile optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (( modified positive solution algorithm ) or ( modified quantile optimization algorithms ))*.
