how to interpret the diagram shown below?

model;

c^(-sigma)=beta*(c(+1)^(-sigma)*(alpha*a(+1)*k^(alpha-1)+(1-
delta)));
y = a*k(-1)^(alpha);

k = i + (1-delta)

*k(-1);*

y = c + i;

log(a) = rholog(a(-1))+ e;

y = c + i;

log(a) = rho

end;

model;

c^(-sigma)=beta*(c(+1)^(-sigma)*(alpha*a(+1)*k^(alpha-1)+(1-
delta)));
y = a*k(-1)^(alpha);

k = i + (1-delta)

y = c + i;

log(a) = rho

end;

can you send me the complete version?
