Hi,

There seem to be two different “Graph” commands, although they have the same name.  
GraphQ does not recognize all graphs. What shall I load in which sequence, if I want to use  
some commands from graphutilities and from combinatorica? Command AdjacencyMatrix  
shows the same problem.

Best,

GG

The Wolfies say in [GraphUtilitiesPackage](http://reference.wolfram.com/language/GraphUtilities/guide/GraphUtilitiesPackage.html)

> As of Version 10, all the functionality of the GraphUtilities package  
> is built into the Wolfram System.

and present a Tutorial _Upgrading from GraphUtilities_ [GraphUtilities](http://reference.wolfram.com/language/Compatibility/tutorial/GraphUtilities.html) ensuring again

> As of Version 10, all the functionality of the GraphUtilities package  
> is built into the Wolfram System.

So, in the best of all worlds - which is by the way just ours - you are allowed to do nothing about it: do not load GraphUtilities any more.

Hi GG,

I think that it is a little bit of a problem to use functionality from both graphutilities and combinatorica at the same time. As the error message says combinatorica is conflicting with the built-in functionality.

I did manage to use functionality from both in one notebook, and switch between the packages, using CleanSlate:  
[http://library.wolfram.com/infocenter/TechNotes/4718/](http://library.wolfram.com/infocenter/TechNotes/4718/)

This piece of code should work after CleanSlate is installed.

(_goto [CleanSlate Package -- from Wolfram Library Archive](http://library.wolfram.com/infocenter/TechNotes/4718/) and   
follow the instructions_)

```
In[1]:= ClearAll["Global`*"]

In[2]:= RandomGraph[{20, 50}]

In[3]:= << Utilities`CleanSlate`

In[4]:= Needs << Combinatorica`
 
In[6]:= GraphPlot[RandomGraph[50, 0.1]]

In[7]:= Names["Combinatorica`*"]

In[9]:= g = RandomGraph[50, 0.1]

In[10]:= ListPlot[DegreeSequence[g]]

In[11]:= CleanSlate["Combinatorica`"]

During evaluation of In[11]:= (CleanSlate) Contexts purged: {Combinatorica`}

During evaluation of In[11]:= (CleanSlate) Approximate kernel memory recovered: 2999 Kb

Out[0]= {"Utilities`CleanSlate`", "TemplatingLoader`", \
"PacletManager`", "System`", "Global`"}

In[1]:= RandomGraph[{20, 50}]

```

It is important that you load “CleanSlate”, before (!) you load Combinatorica. After that you can (in theory) load and unload Combinatorica functionality. The notebook is attached as well. This is not a good solution to your problem, but it might be a first step.

Cheers,

Marco

Hi GG,

you could also call any conflicting or shadowing symbols by their full names, that is, including the name of their context:

```
Combinatorica`Graph

```

is not the same as

```
System`Graph

```

as you can see by evaluating their respective usage messages:

```
?Combinatorica`Graph
?System`Graph

```

I admit that this is a bit cumbersome because of the additional typing work, but it will allow you to access functions of the same name coming from different packages in a controlled way.
