The circle–ellipse problem in software development (sometimes called the square–rectangle problem) illustrates several pitfalls which can arise when using...

It generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its...

great ellipse can be found using the value of γ 0 {\displaystyle \gamma _{0}} . Also determined as part of the solution of the great circle problem are...

1-ellipse is the circle, and the 2-ellipse is the classic ellipse. Both are algebraic curves of degree 2. For any number n of foci, the n-ellipse is...

principal limitations of OOP have been noted. For example, the circle-ellipse problem is difficult to handle using OOP's concept of inheritance. However...

known as a Lamé curve after Gabriel Lamé, is a closed curve resembling the ellipse, retaining the geometric features of semi-major axis and semi-minor axis...

using circle grid strain analysis is to predict potential problems before they become problems. Once you have a forming problem, chances are circle grid...

a circle or ellipse is called a chord. Any chord in a circle which has no longer chord is called a diameter, and any segment connecting the circle's center...

allows one to add, redefine and remove methods at runtime. The Circle-Ellipse Problem is readily solved in CLOS, and most OOP design patterns either disappear...
