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

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

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