Perhaps you should try some spelling variations:
"modified notion optimizer algorithms" » "modified notion optimized algorithms", "modified notion optimized algorithm", "modified notion optimization algorithms"
"modified model solution algorithm" » "modified model evolution algorithm", "modified model convolution algorithms", "modified model evolutionary algorithm", "modified male solution algorithm", "modified model solutions algorithm", "modified nodal solution algorithm", "modified model selection algorithm"

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 model solution algorithm") OR ("modified notion optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( modified model solution algorithm ) or ( modified notion optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified model solution algorithm") or ("modified notion optimizer algorithms"))*.
