This issue came up in #74. The specific post is [here](https://github.com/kdahlquist/GRNmap/issues/74#issuecomment-114299158).We would like to add the following functionality:
The optimization_diagno…

**Initial description**
The objective of this project is to develop a novel closed form Perspective n Point (PnP) pose estimation algorithm for a monocular camera. A variety of techniques have been de…

The stepsize in fmin_bfgs doesn't look robust when the gradient is large, and results in convergence failures.
I tried a few examples with fmin_l_bfgs_b and didn't have any convergence problems.
(asi…

I just looked for the first time in the SVD code. Short message: it is not doing SVD! It's working on the matrix A = JTJ (sorry, cannot superscript T).
Real SVD should work on the Jacobian directly, …

Briefly, the addition of `least_squares` functionality into `curve_fit` contains the following lines
```
else: # if method != "lm"
p0 = _initialize_feasible(lb, ub)
res = least_sq…

Both the already existing `optimize.minimize` and the soon-to-be-released `optimize.least_squares` can take a `bounds` argument (for bounded minimization). `minimize` takes a sequence of `(min, max)`…

Calling `compass.calibrate()` forces the user play some sort of "game" as a side effect.
The behaviour of `compass.calibrateAsync()` has been changed without warning to mimic `compass.calibrate()`.

I am a contributor https://github.com/lmfit/lmfit-py project, which has related functionality. I see that @newville has some commits in here, so I'm sure you're aware.
I like the idea of a lightweigh…

For example,
```
{% math %}{\bf \lambda}^{(t+1)} \leftarrow {\bf \lambda}^{(t)} + \rho({\bf D\beta}^{(t)} - {\bf \gamma}^{(t)}){% endmath %}
Same algorithm applies to a general regularization matrix…
