Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified sales » modified male, modified traces
sales solution » sales evolution, saline solution, water solution

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified sales solution algorithm ) OR ( modified multiobjective optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified sales solution algorithm ) OR ( modified multiobjective optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified sales solution algorithm ) OR ( modified multiobjective optimisation algorithm ))*.
