 varhi := 10; 
varlo := 0; 
npar := 2; 
popsize := 9; 
par := (varhi-varlo)*RandomArray((proc (A) local i; 
if A::(rtable[column]) then 
seq(A(i), i = 1 .. NumElems(A)) else
 args; 
end if 
end proc)
(popsize, npar))+varlo; 
ff := map(proc (x, y) x^2+y^2 end proc, par, 0); 
cost := eval(ff, par);

the values of must assume the first number in row and y the second it´s possible ? please help
