Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified total variation algorithm" » "modified total estimation algorithm", "modified total predation algorithm", "modified total estimation algorithms", "modified global variation algorithm", "modified thermal variation algorithm", "modified ti6al4v variation 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 total variation algorithm") OR ("modified notion optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified total variation algorithm ) or ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified total variation algorithm") or ("modified notion optimization algorithms"))*.
