Perhaps you should try some spelling variations:
"allocation optimization algorithmssssssssssssss" » "allocation optimisation algorithmsssssssssssss", "allocation estimation algorithmssssssssssssss", "allocation estimation algorithmsssssssssssss", "location optimization algorithmssssssssssssss"
"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: (("allocation optimization algorithmssssssssssssss") or ("parameter optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("allocation optimization algorithmssssssssssssss") OR ("parameter optimization algorithms")).
• Removing quotes may allow a broader search: (( allocation optimization algorithmssssssssssssss ) or ( parameter optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("allocation optimization algorithmssssssssssssss") or ("parameter optimization algorithms"))*.
