Hello dear all,
I have been working on the EGC model programmed on GAMS for some time. But at the stage where I am I can not correct the error that appears. In the model resolution, GAMS displays:
STATISTICAL MODEL
BLOCKS OF EQUATIONS 70 SIMPLE EQUATIONS 3,330
BLOCKS OF VARIABLES 71 SINGLE VARIABLES 3,330
NON-ZERO ELEMENTS 14,788 NON-LINEAR NZ 5,928
RESERVOIR BYPASS 20 CONSTANT RESERVOIR 120
CODE LENGTH 15496
FIXED EQUATIONS 3330 FREE VARIABLES 3330
**** SOLVER 1 STATUS Normal completion
**** MODEL STATUS 5 Locally Infeasible
** Disclaimer ** The variance of the derivatives at
initial point is large (= 7.8 ). A better starting point
, better scaling, or better limits on
variables will probably help the optimization.
** Error in Square System: Pivot too small.

**** ERRORS/WARNINGS IN Eq_YH5(M_ru_Moy,2023) EQUATION
1 error(s): Pivot too small.
**** ERRORS/WARNINGS IN VARIABLE Ar(SER,M_ur_Moy,2029)
1 error(s): Pivot too small.
Can anyone help me finalize my resolution. well thank you
NB: You will find attached a copy of the program on GAMS.
