## An optimal day

by: Global Optimization

Yesterday was one of those remarkable days when everything seems just about right. The highlight was an email message I received from a Prof. Fang from Ryerson University notifying us that we had been both nominated and awarded the Omond Solandt Award by the Canadian Operational Research Society for ongoing and outstanding contribution to the field of Operations Research (OR). No, it’s not a Nobel Prize or an Oscar, but whenever a group of smart people publically recognize our work, the honor and pride are genuine.

## Global Optimization Toolbox sensitive to search ra...

Asked by:

Hi

I'm trying to work out how the Global Optimization Toolbox works and I thought I got it working. However, when I increase the ranges of the parameters over which the Toolbox should look for the solution (but still including the previous range), the outcome of the optimization changes, i.e. the toolbox finds different optimal parameter values and a different, and often higher, Sum of Squares (which is my evaluation criterium). I don't understand what I'm doing wrong!

An example:

Asked by:

Hi

Just started using the global optimization toolbox. Not sure if I am doing something wrong or if it is genuinely awful. After about 20mins it produces a fit that is dreadful,an alternative cheaper package (scop) produces a great fit in about 2 mins. Can anyone see what I'm doing wrong?

## An easy way to plot regions between two curves...

Asked by:

It’s a pity that Maple does not offer easy ways to plot the region between two curves in the xy-plane. The option “filled=true” can only plot the region between the curve y=f(x) and the x-axis.

## ODE Analyzer...

Asked by:
I am using the ODE analyzer to look at the numerical solution to a second order ODE of the form 0=-uc'-kc+Ec" with u=.3, k=.0001 and E=10, and with conditions, c(0)=2 and c'(20,000)=0. When I try the solve numerically, I get an error message saying "unable to convert input to a first order system. Recieved error: too few boundary conditions, expected 5 got 2." What am I missing?

## MapleNet worksheet problem - fail to load the work...

Asked by:
Hallo, I would like to run my worksheet document (.mw) on MapleNet server. Unfortunately, I have always got this error message "Maple Worksheet - Error, Failed to load the worksheet /maplenet/kriz/taylor.mw". I found MapleNet Demo on our server (http://melian.ics.muni.cz:8080/maplenet/worksheet/) but with the same error result. Maybe there is some problem on our server, but me and our administrator don't have any idea to correct it. Thank you for help. Regards Pavel Kriz kriz@math.muni.cz Masaryk University Czech Republic
