I'm not sure if there's something on the page I'm not seeing but even  https://www.maplesoft.com/support/help/Maple/view.aspx?path=Optimization/Minimize#examples

 

Maximize(2*x^2 + 2*y^2 + y, {2*x + y <= 6, y^2 - x <= 2})

a literal copy-paste of the posted example maple just repeats what I posted Idk whats wrong. btw is there some way to read the maple documentation pages?

 

maple save variables is greyed out  would anyone happen to know why this could be the case?

                       tmmp := [1, 10 q]
                            PS1 := 1
                          PS2 := 10 q
                           [1, 10 q]
                        tnmp := [8, 5 q]
                            QS1 := 8
                           QS2 := 5 q

 

gP, gQ, S1, S2, P1, P2, Q1, Q2

(q*x + 9*q + y)^33*(4*q*x + 6*q + y)^16/((x + 3)^48*(x + 10)), (q*x + 9*q + y)^33*(4*q*x + 6*q + y)^16/((x + 3)^48*(x + 10)), 8, 6*q, 1, q, 1, -10*q    

Normal(Eval(gP, {x = QS1, y = QS2})*Eval(gQ, {x = S1, y = -S2})*1/(Eval(gP, {x = PS1, y = PS2})*Eval(gQ, {x = S1, y = -S2}))) mod p;
Error, (in mod/Normal) invalid arguments or not implemented
 

P1 := 1;
Q1 := 1;
P2 := q;
Q2 := -10*q;
p - 11;
                            P1 := 1
                            Q1 := 1
                            P2 := q
                          Q2 := -10 q
                               0
NULL;
if Q2 = P2 mod p then
    return 42;
else
    return 0;
end if;
(P2 - Q2) mod p;
                               0

I don't know why but   (p=11)   here the code below does not return 42  and 

evalb(Q2 = P2 mod p);      returns
                             false   

Error, invalid subscript selector
WeilP:
   7       PS1 := temp[1];
============================================

WeilP:=proc(m, P1, P2, Q1, Q2, f, p) 
local S1, S2, gP, gQ, temp, PS1, PS2, QS1, QS2;
    if [P1,P2] = [Q1, Q2] mod p then
        return 1 ;
        else  
            # [S1, S2] := EAdd( f, x, P1, P2, Q1, Q2); 
            temp := EAdd( f, x, p, P1, P2, Q1, Q2);
            S1:= temp[1];
            S2:=temp[2];
        temp := EAdd( f, x, p, P1, P2, S1, -S2);   #represents P-S  
            PS1:= temp[1];
            PS2:=temp[2];
        temp := EAdd( f, x, p, Q1, Q2, S1, S2);    #Q+S
        QS1:=temp[1];
        QS2:=temp[2];
    #        gP:=Weil( m, P1,P2, f, p ); 
    #        gQ:=Weil( m, Q1,Q2, f, p );
    return 0
#    return Normal(  ( Eval(gP, { x=QS1, y=QS2 } ) * Eval(gQ, {x=S1, y= -S2} ) )  / ( Eval(gP, { x=PS1, y=PS2 } ) * Eval(gQ, {x=S1, y= -S2} ) )   )  mod p;    # ( f_P(Q+S) f_Q(-S)  ) / ( f_Q(P-S) f_P(S)  )
    end if ;

Here EAdd is elliptic curve addition   

I tried evaluating the code outside the code edit region and it seemed to work okay  temp ends up being the vector 

p.s. how do I get maple to save the values of a procedure rather than deleting them? 

how do I view variable values during debugging?
