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