Convert undirected graph unweighted graph to a weighted graph even though all the weights are 1

as i want to check how my function works on weighted graph as I know it works unweighted

Yesterday (?) there was a nice question which was answered by VV using Jensen's inequality.

Where is it now?

I teach high school math where we use Maple. Some times some students who use Maple 2022 on Mac computers both older and new version of the OS, experience that the document won't react to simple things like plot, solve of loading packages with the "with" command. 

Any idea could be causing this? Because the error goes away if we load a new document within Maple or restart the program.

Found integration problem which causes server.exe to crash each time. I hope this can be used to help find why server.exe keeps crashing much more than before in Maple 2022.

This happens each time. The above is a typical example of what I have been saying all the time above server.exe crashing. It should not do that. If it can not solve the problem, it should simply return.

I hope these problems will be fixed in Maple 2023.

Any one can figure why it crashes?

This question stems from a previous question that has been perfectly resolved by acer and Carl Love, but as Carl Love mentioned the foldl function, today I attempted to experience its functionality (In order to understand the foldl or foldr function). But I encountered a small issue. 

s:="[ (0, 1), (1, 2), (1, 10), (2, 3), (3, 4), (4, 5),
(4, 9), (5, 6), (6, 7), (7, 8),(8, 9), (10, 11), (11, 12),
(11, 16), (12, 13), (13, 14), (14, 15), (15, 16)]";
with(StringTools):
L1:= "()[]": L2:= "{}{}":
X:=foldl(SubstituteAll,s,op([L1[1],L2[1]]),op([L1[2],L2[2]]),op([L1[3],L2[3]]),op([L1[4],L2[4]]));

Error, (in StringTools:-SubstituteAll) expecting 3 arguments, but got 2

I find it strange that foldl doesn't recognize SubstituteAll with three arguments. 

Isn't s and op([L1[i], L2[i]]) providing three arguments? Of course, s is constantly changing.

The goal is to replace the above string with:

{ {0, 1}, {1, 2}, {1, 10}, {2, 3}, {3, 4}, {4, 5},

    {4, 9}, {5, 6}, {6, 7}, {7, 8},{8, 9}, {10, 11}, {11, 12},

    {11, 16}, {12, 13}, {13, 14}, {14, 15}, {15, 16}}

Hey
My notes from my math course is corrupt and i really need them. When i open the document it just say "worksheet may be incomplete" Can anyone help recovering them? I tried the recover function but it didn't work. Here is the original document: Mat_1_-_Noter.mw. 

I also have this .bak from the day before where i know it worked:   _Users_jonathanlarsen_Desktop_Mat_1_-_Noter70_MAS.bak.zip
How can i prevent this in the future? It's the second time it has happenend.

Sincerely a frustrated student :(

For instance, here is a list of valid "rules" (given as equations): 

(* restart; *)
rules := [g = d, e = a, a = b, f = d, c = g, b = b, d = c, c = f, a = e]:

But these rules can be represented more compactly as a list of "cycles": 

cycles := [[g, d, c], [e, a], [f, d, c], [b]]:

Is there a efficient way to convert into ? 

Hey guys

I have a question using the piecewise function:

fa := unapply(piecewise(0 < x and x < a, k1, a < x and x < b, k2), x);

simplify(fa(x)) assuming 0 < a, 0 < x and x < a;

It should return k1, but it doesn't. Does anyone have a solution?

Sincerely,

Oliveira

Suppose I have a polynomial:

poly := x^6 - 3*x + 3

And I know one of its roots and its galois group:

firstroot := [solve](poly, x)[1]:
G := GaloisGroup(poly, x):

Since G act transitively on the all roots. How do I get all the other roots of this polynomial just by the firstroot and G, but not by solving the equation.

I would like to set a axis lable as  A (kg/m³)

where A is in italic style, (kg/m³) is in normal style

Is there documentation that tells about what the dollar sign means and how to manage it. It just appears in recent releases and it didn't used to in older releases. It is distracting and seems to appear randomly.

Thanks

I've been using Maple Flow for awhile and generally pleased with its performance...until today.

Going through my normal workflow, the sheet stopped evaluating and a little troubleshooting later it seems that the issue is that once I use a keyboard shortcut to include units, the sheet will not evaluate anything going forward. 

Once

I have to maximize my non linear objective function TBCI (given in attached worksheet) with 4 inequality constraints. The decision variables are i and q.The range of i is 0 to 1 and of q is 0 to 76.

When i tru to solve it using NLP solve it is showing error-"Error, (in Optimization:-NLPSolve) constraints must be specified as a set or list of equalities and inequalities".

Please help me to solve it. please find attached the maple file

For instance, Hypergeometric0F1Regularized^(1,0)[1,1.] = -0.113894... as given in Mathematica. I was wondering how this type of regularized hypergeometric function is defined in Maple.
