Perhaps you should try some spelling variations:
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"
"modified ohca solution algorithm" » "modified ohca evolution algorithm", "modified ohca convolution algorithms", "modified ohca evolutionary algorithm", "modified orca solution algorithm", "modified nacl solution 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 ohca solution algorithm") OR ("modified objective estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified ohca solution algorithm ) or ( modified objective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified ohca solution algorithm") or ("modified objective estimation algorithms"))*.
