Perhaps you should try some spelling variations:
"notion optimization algorithmssssssssssssssssssss" » "notion optimisation algorithmsssssssssssssssssss", "notion estimation algorithmssssssssssssssssssss", "notion estimation algorithmsssssssssssssssssss", "network optimization algorithmssssssssssssssssssss", "policy optimization algorithmssssssssssssssssssss", "allocation optimization algorithmssssssssssssssssssss"
"parameter optimization algorithms" » "parameter optimisation algorithm", "parameter estimation algorithms", "parameter estimation algorithm", "parameters optimization algorithms"

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: (("notion optimization algorithmssssssssssssssssssss") or ("parameter optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("notion optimization algorithmssssssssssssssssssss") OR ("parameter optimization algorithms")).
• Removing quotes may allow a broader search: (( notion optimization algorithmssssssssssssssssssss ) or ( parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("notion optimization algorithmssssssssssssssssssss") or ("parameter optimization algorithms"))*.
