L2SMEA sometime generates errors

[Md-Ashraful-Pramanik]

Sometimes I get the following error while running platemo('problem',@CEC2010_F1,'algorithm',@L2SMEA, 'maxFE', 100, 'D', 1000);

Unrecognized method, property, or field 'ojs' for class 'SOLUTION'.

Error in UpdateArchive (line 33)
        TArchive    = [TArchive;popNew(topRemain,1:D),NewSolution.ojs];

Error in L2SMEA/main (line 79)
                [TArchive,Archive] = UpdateArchive(TArchive,Problem,Offspring, Archive);

Error in ALGORITHM/Solve (line 80)
                obj.main(obj.pro);

Error in platemo (line 99)
            Algorithm.Solve(Problem);
