His "numerical steps" were literally a computer program, albeit a simple one carried out by people cranking noisy calculating machines.
In this particular case, we worked out all the numerical steps that the machines were supposed to do — multiply this, and then do this, and subtract that.
In his 1975 lecture "Los Alamos From Below," Feynman described his solution: In this particular case, we worked out all the numerical steps that the machines were supposed to do — multiply this, and then do this, and subtract that.
In this paper, a numerical step-by-step approach is developed to estimate shakedown limits of pavements with Mohr Coulomb materials.
Furthermore, existing lower-bound shakedown solutions for pavements are extended, in an approximate manner, to account for the change of material dilation angle and the shakedown results obtained in this way agree well with those obtained through the numerical step-by-step approach.
The other boundary conditions and numerical steps are the same as those in the previous 2-D modeling example.
The presented method, based on combining symbolic and numerical steps to the approximation problem, provides approximate parameterizations of space algebraic curves from a small number of approximating arcs.
From a methodological point of view, the scope of the present paper is to illustrate the appropriate numerical steps in order to assure reliable atmospheric flow predictions in complex terrain.
