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 pulses optimizer algorithms" » "modified pulses optimized algorithms", "modified pulses optimized algorithm", "modified pulses optimization algorithms", "modified pulse optimizer algorithms", "modified pulsed optimizer algorithms"

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

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