How do I find the straightest path through 3D rectangles?
I'm mainly a programmer, not a mathematician, so please bear with me.
I have a sequence of rectangles in 3D space. Each one has a specified pose: position, an orientation (rotation in 3D), and a width ...

SOCP standard form
I have the following concave optimization problem
$$\max_x \; c^\top x - \sum_{i=1}^n \left( \lvert x_i \rvert + \lvert x_i \rvert^{3/2} \right) $$
I am able to solve it numerically using SOCP solvers,...

Projection onto a generic second-order cone
I am looking for an analytical formulation of the projection of a generic vector $\mathbf{v}\in\mathbb{R}^3$ onto the second-order cone $\|\mathbf{x}\|\le\mathbf{c}^T\mathbf{x}$. While I was able to ...

Optimize a convex difference of quad forms
I have an optimisation problem of the form:
$$\min_x c^T x + \| V x\|^2_2 + \| D x\|^2_2 - \| W x\|^2_2$$
Subject to linear constraints.
$D$ is diagonal and $V$, $W$ are non-square matrices. I know ...

Is there an SOCP presentation of power of non-convex term for this constraint $\frac{1}{4}{\left( {1 + xyz} \right)^2} \le t$?
I am a network engineer who is currently working with some network optimization problem. In my problem the term $\frac{1}{4}{\left( {1 + xyz} \right)^2}$ appears on the objective function and I can ...

Can geometric programming be considered as a special case of second order cone programming?
From the Mosek cookbook, it is clear that by using the log-sum-exp transformation and some extra variable $u_k$, a geometric programing problem can be transform into a exponential cone presentation.

reduction from QCQP to SOCP
Suppose a QCQP problem :
$$ \min_{x\in\mathbb{R}^{n}}f\left(x\right)=\frac{1}{2}x^{T}P_{0}x+q_{0}^{T}x$$
$$ s.t:\begin{cases}
\frac{1}{2}x^{T}P_{i}x+q_{i}^{T}x+r_{i}\le0 & i=1,2\dots,m:m\le n

Proof regarding center of an optimal Euclidean ball containing distinct points
Suppose we are given $k$ distinct points $a_i \in \mathbb{R}^n$ for $i = 1, 2, \dots, k$, and our objective is to determine the Euclidean ball with the smallest radius that contains all these points ($...
