Hi,
I have a emp syntax error for a equilibrium problem. GAMS said “JAMS Pre processing failed” caused by “EMP syntax error: key expected: is I (item 13 on line 3) but instance not in variable rim”.
My code is following:
- set defined
set agent /a1a2/,
time /t0t2/,
node /n0n12/,
j /j1j3/,
k /k1k4/;
alias(n, node, parent, child);
alias(a, agent);
set sn(n) /n1n12/
leafn(n) /n4n12/
parentn(n, node) /(n1n3).n0,
(n4n6).n1,
(n7n9).n2,
(n10n12).n3/;
Parameter
y(n) /(n1n3) 5,
