Ruby Graph Library

Ruby Graph Library (RGL)

RGL is a framework for graph data structures and algorithms.
The design of the library is much influenced by the Boost Graph Library (BGL) which is written in C++ heavily using its template mechanism. Refer to www.boost.org/libs/graph/doc for further links and documentation on graph data structures and algorithms and the design rationales of BGL.
A comprehensive summary of graph terminology can be found in the the graph section of the Dictionary of Algorithms and Data Structures at www.nist.gov/dads/HTML/graph.html.

Sirupsen and his codeabouts: I’ve always run Ruby, and I’ve always used RVM. But it’s not until recently when I attended Aarhusrb and @chopmo gave a talk on RVM, that I realized how wrong I was using RVM. Basically, I’m somewhat always using system Ruby, installing all gems with sudo

A simple rebase git command to rewrite history

Posted on October 30, 2011 by admin

I have a repository in github where I plan to push the work for the exercises of ml-class.org

Having completed the exercises 1 and 2 onto my master branch, here is what my git history looked like :

 (master) $ git lg
* fe0fea7 - (HEAD, master) 0-plot data (Nicolas Rolland 7 days ago)
* da30d65 - 5-6-costfunctionreg et gradient (Nicolas Rolland 7 days ago)
* 6c1f4a3 - 4-predict (Nicolas Rolland 7 days ago)
* 22f6d98 - 2- cost function (Nicolas Rolland 7 days ago)
* c1e50ce - 1-sigmoid (Nicolas Rolland 7 days ago)
* 76c8b48 - 2nd exercize (Nicolas Rolland 7 days ago)
* bf9f683 - normal eqtn price estimation (Nicolas Rolland 8 days ago)
* 5cd7d0b - normal eqtn (Nicolas Rolland 8 days ago)
* 1eefdd5 - estimate house price (Nicolas Rolland 8 days ago)
* b2aca44 - rate learing plot (Nicolas Rolland 8 days ago)
* 617423e - gradientdescentMulti (Nicolas Rolland 8 days ago)
* 1b2d951 - computecostMulti (Nicolas Rolland 8 days ago)
* bba2916 - featurenormalize (Nicolas Rolland 8 days ago)
* fe7ba87 - gradientdescent (Nicolas Rolland 8 days ago)
* 637efdd - computecost (Nicolas Rolland 8 days ago)
* 1d0d2e2 - plotData (Nicolas Rolland 8 days ago)
* dc297c9 - warmup (Nicolas Rolland 8 days ago)
* fd7b7fa - first exercize (Nicolas Rolland 8 days ago)
* 355e42a - first commit (Nicolas Rolland 8 days ago)

That is, a nice sequential history. I decided, ~~for reasons that are still behind my full conscious knowledge at this time~~, in order to push each exercise independently on github, to create a topic branch for each exercise. Therefore I added some branch, by simply typing

(master) $ git co bf9f
(master) $ git branch exo1
(master) $ git co master
(master) $ git branch exo2

That sets the branch name all right, but my branch exo2 contains the history of exo1.

It turns out it is quite easy to selectively apply only the change from exo1 to exo2 to a certain starting point, in my case, the first commit 355e42 :

 (master) $ git rebase --onto 355e42 exo1 exo2
First, rewinding head to replay your work on top of it...
Applying: 2nd exercize
Applying: 1-sigmoid
Applying: 2- cost function
Applying: 4-predict
Applying: 5-6-costfunctionreg et gradient
Applying: 0-plot data

And voila.
If I check my log I can see :

(exo2) $ git lg
* e3ee4ea - (HEAD, exo2) 0-plot data (Nicolas Rolland 6 seconds ago)
* 3d58766 - 5-6-costfunctionreg et gradient (Nicolas Rolland 6 seconds ago)
* 8743366 - 4-predict (Nicolas Rolland 6 seconds ago)
* 6c327e9 - 2- cost function (Nicolas Rolland 6 seconds ago)
* ac916d3 - 1-sigmoid (Nicolas Rolland 6 seconds ago)
* f3db3f1 - 2nd exercize (Nicolas Rolland 6 seconds ago)
* 355e42a - first commit (Nicolas Rolland 8 days ago)

So my exo2 branch has no knowledge of the modifications from exo1.
I came from a single linear history and split that into 2 different branches independent of each other.

Reshape package: “While you are probably familiar with the idea of reshaping, it is useful to be a little moreformal. Data reshaping involves a rearrangement of the form, but not the content, of the data.Reshaping is a little like creating a contingency table, as there are many ways to arrange the same data, but it is different in that there is no aggregation involved. The tools presented in this paper work equally well for reshaping, retaining all existing data, and aggregating, summarising the data, and later we will explore the connection between the two.”
