How to cmaple or mw file maple dualaxisplot output to jpeg file after press and run?

How to cmaple print int(f(x),x) after append to text command instead of /

                                             |

I use append and cmaple to run

originally can See result in real time even if open text file

but suddenly text file become 0KB

when I copy text file and paste 

0 KB become 3 KB 

but the program can not further output to text file and no error shown

Error

can not raise the datalimit above hard limit

my new notebook has 32GB memory

kernelopts(datalimit=28*unit(gibibtye)):

do i need to assign datalimit with kernelopts?

and

I remember i set a trick to protected this file

now I can read and run 

but return above error

does it mean that I do not need to set limit?

Minimise(eq1, {eq2>=0,eq3>=0,eq4>=0, a1<>0,a2<>0,a3<>0,a4<>0})

can not handle strict inequalities error

Is there extendable combinatorics experiment architect system design

such as new method can combine or use with old method and find relationship between them , these kind of big data system design in combinatorics experiment design?

Hi

I have an optimization problem subjects with a system of ordinary differential equations with initial conditions.

I would like to obtain u^star, x^star and y^star solution of my problem 

I prefer if possible we implement hamilton jacobi bellman if possible

Which sorting related with famous sequence

for example 

sorting differential equation in a list

then access the list with famous sequence as index such as using https://oeis.org/

after access with sequence as index, use choose function to get combinations then most result are isomorphism differential ideals?

is there methods about this sorting in Richard Stanley Combinatiric book? which page of it?

Last month I still can read file

by 

read “c://Users//hello//Documents//h.m”

but

now it return error

no read access c://Users//hello//Documents/

and

but still the same error

i unencrypted m file by window properties

still the same error

i save file into maple roaming directory under 12 folder , still the same error

i save into maple installation directory maple 12 , still the same error
