Perhaps you should try some spelling variations:
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
co algorithm » mom algorithm, _ algorithm, our algorithm
code based » model based, coal based, income based
based co » based code, based no2, based two

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 optimisation algorithm ) or ( code based co algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified objective optimisation algorithm ) OR ( code based co algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimisation algorithm ) or ( code based co algorithm ))*.
