Perhaps you should try some spelling variations:
"modified choosing optimization algorithms" » "modified choosing optimisation algorithm", "modified choosing estimation algorithms", "modified choosing estimation algorithm", "modified staffing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimization algorithms"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"

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 solution algorithm") OR ("modified choosing optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective solution algorithm ) or ( modified choosing optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithm") or ("modified choosing optimization algorithms"))*.
