Perhaps you should try some spelling variations:
"modified adaptive estimation algorithms" » "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive optimisation algorithm", "modified adaptive ventilation algorithms", "modified quantile estimation algorithms", "modified adaptive quantization algorithms", "modified passive estimation algorithms"
"modified invasive solution algorithm" » "modified invasive evolution algorithm", "modified invasive convolution algorithms", "modified invasive evolutionary algorithm", "modified passive solution 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 invasive solution algorithm") or ("modified adaptive estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive solution algorithm") OR ("modified adaptive estimation algorithms")).
• Removing quotes may allow a broader search: (( modified invasive solution algorithm ) or ( modified adaptive estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive solution algorithm") or ("modified adaptive estimation algorithms"))*.
