Perhaps you should try some spelling variations:
"modified static optimisation algorithmss" » "modified static optimization algorithms", "modified static estimation algorithms", "modified static estimation algorithm", "modified static optimization algorithmsss", "modified static estimation algorithmss", "modified static estimation algorithmsss", "modified static optimization algorithmss", "modified stage optimization algorithmss", "modified stochastic optimization algorithmss"
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified static optimisation algorithmss") or ("modified allocation optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified static optimisation algorithmss") OR ("modified allocation optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified static optimisation algorithmss ) or ( modified allocation optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified static optimisation algorithmss") or ("modified allocation optimisation algorithm"))*.
