A saddle point is a point in the range of a smooth function every neighbourhood of which contains points on each side of its tangent plane.

what way did point B move relative to point A?
Eight point four. Eight point four. Eight point four. Eight point four.
An inflection point is not a saddle point, but a saddle point is an inflection point. To be precise, a saddle point is both a stationary point and an inflection point. An inflection point is a point at which the curvature changes sign, so it is not necessary to be a stationary point.

The low point of a mountain ridge is called a col or a saddle. It is the point where two slopes converge and is often a pass or a corridor between two peaks.
There will be no saddle point; no point in the table will be an optimum.
A saddle in geography refers to a low point or dip between two higher points on a ridge or mountain. It has a characteristic saddle shape, resembling a horse saddle, hence the name. Saddle points are important features for hiking and mountaineering as they often provide a passageway or route to cross over a mountain ridge.
When looking at a horse saddle, the saddle point (i.e. the centre) is the lowest point on the structure in the longitudinal plane whilst also being the highest point on the structure in the lateral plane. Therefore it can be considered geometrically to simultaneously be a point of maximum and minumum height in space. This describes well the equilibrium situation in game theory where the agent tries tominimize the maximum possible loss. Alternatively, it can be thought of as maximizing the minimum gain (maximin).
A saddle point in nuclear fission refers to the point in the potential energy landscape where the nucleus is elongated enough to undergo fission. At this point, the nucleus is temporarily stabilized before separating into two fission fragments. It is a crucial stage in the fission process.
