Perhaps you should try some spelling variations:
"modified market optimization algorithm" » "modified market optimization algorithms", "modified market optimisation algorithm", "modified market estimation algorithm", "modified game optimization algorithm", "modified parameter optimization algorithm", "modified market capitalization algorithm", "modified male optimization algorithm"
"modified adaptive ventilation algorithm" » "modified adaptive estimation algorithm", "modified adaptive estimation algorithms", "modified adaptive evolution algorithm", "modified adaptive quantization algorithm", "modified invasive ventilation algorithm", "modified passive ventilation algorithm"

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

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