Exact solution of linear equations
Proceedings of the second ACM symposium on Symbolic and algebraic manipulation - SYMSAC '71, 1971The congruential method of obtaining the exact solution of a system of linear equations with integral coefficients is critically reviewed. A new and efficient test for checking that a sequence of residue solutions determines the correct integer solution of the system of equations is presented.

On exact solutions of the Schrodinger equation
Journal of Physics A: Mathematical and General, 1983In the one- and three-dimensional Schrodinger equation, a broad class of the regular potentials (rational functions of the rational powers of r) may admit exact bound-state solutions in the generalised harmonic-oscillator elementary form psi (r)=rsigma *polynomial*exp(-polynomial).

Faster Exact Solutions for Max2Sat
2000Given a boolean 2CNF formula F, the MAX2SAT problem is that of finding the maximum number of clauses satisfiable simultaneously. In the corresponding decision version, we are given an additional parameter k and the question is whether we can simultaneously satisfy at least k clauses. This problem is NP-complete.

Some Exact Solutions of Magnetohydrodynamics
The Physics of Fluids, 1963Four examples of the exact solutions of two-dimensional magnetohydrodynamics of incompressible inviscid fluid are given. Two are valid for infinite conductivity and the other two for finite conductivity.
