[sage-support] Re: sage notebook worksheets lost content
Thanks for the suggestion. Unfortunately, it looks like all my workbooks were somehow trashed some time between the 25th and 29th of May this year. I might take a look through this newsgroup to see if it's a known issue. I guess I might have to accept that I lost all my work. On 18 Aug, 15:47, Marshall Hampton hampto...@gmail.com wrote: There might be a better way to do this, but here is one way: In a cell of your worksheet, do: %sh ls -t ../../snapshots |head which will give you a list of the most recent snapshots of your worksheets. For my worksheet, the most recent one was called: 1250606636.bz2. So then you can do: %sh cp ../../snapshots/1250606636.bz2 . and you will get a link to that compressed worksheet snapshot. You could then unpack it, and then paste it in after clicking Edit in the notebook. That's a little tedious if you have lots of worksheets lost in this way - it might be possible to restore all of them with a script, but I'm not sure exactly how to do that on sagenb.org. -Marshall Hampton On Aug 18, 9:26 am, bsdz blai...@googlemail.com wrote: Hi I just checked back at my workbooks onwww.sagenb.organdfound most of my workbooks have had their content replaced with a single e character.

[sage-support] using minimize_constrained
Hi, how do I go about substituting the results from functions such as
minimize_constrained back into the function that was trying to
minimize? For example, if I have
x,y = var('x y')
f = x*y
(admittedly a trivial example) and I want to minimize the function
over the range x in [1,10] and y in [1,10], I would use
a = sage.numerical.optimize.minimize_constrained(f,[(1,10),(1,10)],
(5,5))
and get back
a = (1.0,1.0)
If I try the command
f((1.0,1.0))
I get an error and any similar attempt also gives me an error. If I
had a dictionary of values for the result of minimize_constrained, I
would use .substitute(). Functions like optimize.linear_program by
default return a dictionary of values and functions like find_fit
offer the option of returning a dictionary of values (through the
solution_dict argument) but minimize_constrained doesn't seem to offer
anything similar.
I am dealing with functions with a nonconstant number of variables, so
I can't do anything like
.substitute(x=a[0])
Suggestions would be greatly appreciated,
Greg

Something quite useful in python: If a function expects some
arguments, and you have a list/tuple of things that you want to use as
the function's arguments, then you can do so by prepending * to the
function. Similarly, you can pass in a dictionary by prepending **.
In this case, you get an answer, but also a deprecation warning:
sage: f(*a)
/usr/local/sage/local/lib/python2.6/site-packages/IPython/iplib.py:
2073: DeprecationWarning: Substitution using function-call syntax and
unnamed arguments is deprecated and will be removed from a future
release of Sage; you can use named arguments instead, like EXPR(x=...,
y=...)
exec code_obj in self.user_global_ns, self.user_ns
1.0
This is because you defined f not as a function, I guess.
Defining
sage: f(x,y) = x*y
allows to do
sage: f(*a)
1.0
without a deprecation warning.
But, alas, sage.numerical.optimize.minimize_constrained fails to work
if f is defined like this.
Possible, but not nice, seems
sage: f = x*y
sage: a = sage.numerical.optimize.minimize_constrained(f,[(1,10),
(1,10)],(5,5))
sage: f.function(x,y)(*a)
1.0
Hopefully someone knows a more natural solution.
Cheers,
Simon

Yes, this is what I meant by more natural solution. Sorry, I didn't
know the exact syntax of minimize_constrained, so I thought the
argument f (as a function in two variables) would be fine.
