RSIC COMPUTER CODE PSR-079
1. NAME AND TITLE
AMARA: Nuclear Data Adjustment Using Lagrange's Multipliers Method.
CNEN Nuclear Research Center, Casaccia, Italy.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 360/370.
4. NATURE OF PROBLEM SOLVED
The evaluation of adjusted nuclear parameters by means of correlation with integral data generally
involves the inversion of a given matrix. Since, in general, the number of nuclear data is large with
respect to that of integral experiments, AMARA was developed to reduce the linear dimensions of the
matrix to be inverted to the number of integral data.
5. METHOD OF SOLUTION
AMARA performs nuclear data adjustment using Lagrange's multipliers.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for AMARA.
8. COMPUTER HARDWARE REQUIREMENTS
AMARA is operable on the IBM 360/370 computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran IV compiler is required.
