Perhaps you should try some spelling variations:
"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"
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"

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