The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent.
A horseshoe curve is a means to lengthen an ascending or descending grade and thereby reduce the maximum gradient. Grade or gradient is defined as the rise divided by the run (length) or distance, so in principle such curves add to length for the same altitude gain, just as would a climbing spiral around one or more peaks, or a climbing traverse (cutting) wrapping around an end of a ridge.
The gradient of F is then normal to the hypersurface. Similarly, an affine algebraic hypersurface may be defined by an equation F(x 1, ..., x n) = 0, where F is a polynomial. The gradient of F is zero at a singular point of the hypersurface (this is the definition of a singular point). At a non-singular point, it is a nonzero normal vector.

Compensation for curvature: the gradient is slightly eased on sharpest curves so that the tractive effort to pull the train is uniform. Horseshoe curves; Spirals; Zig zags; A descending momentum gradient on the approach to a hill allows a train to increase speed before a climb. [1]
Hill climbing attempts to maximize (or minimize) a target function (), where is a vector of continuous and/or discrete values. At each iteration, hill climbing will adjust a single element in and determine whether the change improves the value of ().
Miles Cross Hill is a large hill that is the sloping gradient up to the landscape of the Lincolnshire Wolds. [1] As it is the first large hill of the Wolds, there are views of the Lincolnshire Fens and Coast.
