I'm new to these problems both mathematically and programmatically. If anyone could suggest a c++ library to use that could solve the following problem I would really appreciate it.
Given constants:
{x_1, ..., x_n}, {y_1, ..., y_n}, {z_1, ..., z_n},…

JavaScript operator for "within x of"
is there a JavaScript operator that will check proximity, kind of like a soft equals? For example, instead of if (a == b) it would read if (a is within 5 of b). There is probably no such thing but it would be a big help if there was.
thank you

Plotting constraints in 3D
I would like to be able to visualise a volume (or the surface representing its bound) defined by constraints in 3D.
More precisely, I have some constraints, for example
f0(x,y,z)=(( not ((157.0/1.0) < (((-20.0/1.0) * (y)) + ((-380.0/1.0) * (x)))) )…

Fitting 16 variables in 17 inequalities in Python
I have 17 inequalities:
1: (x[0] + x[1] + x[2] + x[4] + x[6] + x[7])/(x[0] + x[1] + x[2] + x[3] + x[4] + x[5] + x[6] + x[7]) >= 0.4
2: (x[3] + x[5])/(x[0] + x[1] + x[2] + x[3] + x[4] + x[5] + x[6] + x[7]) <= 0.6
3: x[0]/(x[0] + x[1] + x[2] + x[3]…

Using matplotlib, is there a way to create simple 2d plots of basic inequalities
How can one creat a simple, 2 dimensional plot of a basic inequality. The result is a numbered line with one or two lines overlaid. The line or lines would begin or end with an arrow, a filled-in circle, or an open circle.

Frechet Bounds inequality
In the Frechet Bounds inequality equation,
max(0, P(A) + P(B) − 1) ≤ P(A & B) ≤ min(P(A), P(B))
I can totally understand the intuition behind the minimum value of P(A & B) to be "0" and maximum value to be minimum of "P(A) and P(B)" but in what…
