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