set i;
set i /1,2/;
set i(*);
The GAMS compiler gets confused if i is used as domain:
1 set i;
2 parameter p(i);
3 set i /1,2/;
4 set i(*);
**** $184
**** 184 Domain list redefined
Work-around: make sure line 1 and 4 use both i or i(*).
Hi, I'm a first year undergrad and I'm currently working on a gams problem. I have written out my code but i keep getting errors of 'symbol redefined for with a different type', 'domain list redefined' and 'domain violation for set'. Can you help me please?
ReplyDeleteThis is my code:
Sets
i stream1 /C2H2/
j stream2 /CO2, O2, N2, H2O/
k stream3 /CO2, N2/
l stream4 /H2O/
m stream5 /O2, N2/
n stream6 /CH4, CO2, N2/
o stream7 /H2O /
p stream8 /H2 /
q stream9 /H2O /
r stream10 /H2O /
s stream11 /O2 /
t stream12 /H2O/
u stream13 /N2/
v stream14 /O2, N2/;
Parameters F(i), alpha_O2(v);
*where F is the mass flow rate and alpha is compositions of each component in the stream
F(i)=100;
alpha_O2(v)=0.21;
Variables F(j),F(k),F(l), F(m),F(n),F(o),F(p),F(q),F(r),F(s),F(t(,F(u),F(v),alpha(j), alpha(k), alpha(l), alpha(m), alpha(n), alpha(v), r_11, r_22, r_33;
