Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
co algorithm » mom algorithm, our algorithm, _ algorithms
_ algorithm » _ algorithms, _ algorithmic, mom algorithm
code based » model based, coal based, income based
parameter » parameters

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code based ((co algorithm) OR (_ algorithm)) ) or ( modified parameter optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( code based ((co algorithm) OR (_ algorithm)) ) OR ( modified parameter optimization algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code based ((co algorithm) OR (_ algorithm)) ) or ( modified parameter optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( code based ((co algorithm) OR (_ algorithm)) ) or ( modified parameter optimization algorithm ))*.
