Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"model using open algorithm" » "model using mppt algorithm", "model using our algorithm", "model using driven algorithm", "code using open algorithm", "models nursing open algorithm", "powder using open algorithm", "model using opencl algorithm", "model using one algorithm"

Try widening your search to All Fields.

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

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