Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified notion estimation algorithms", "modified network optimization algorithm"
"modified dispersive solution algorithm" » "modified dispersive evolution algorithm", "modified dispersive convolution algorithms", "modified dispersive evolutionary 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 dispersive solution algorithm") OR ("modified notion optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified dispersive solution algorithm ) or ( modified notion optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified dispersive solution algorithm") or ("modified notion optimisation algorithm"))*.
