## Strange Optimization Output...

Maple 2020

Hello everyone

I observe the following "strange" case and I am wondering if I am missing something. So, any insights are more than appreciated. The case is the followin:

When I use

with(Optimization):
Interactive(x + y, {x = 0 .. 1, y = 0 .. 1, 1 <= x + y})

I get: objective =1, x=y=.5

However, If I run

with(Optimization):
Minimize(x + y, {x >=0,x<=1, y>=0,y<=1, 1 <= x + y})

then I get: objective =1, x=1, y=0

Why there is such a difference? Because of there are multiple solutions?

## Solving inequality with one variable and...

Maple

Hello to everyone,

I want to solve the following inequality:

solve(b^4-(2-d)*b^2-2*d*b+1+d > 0, [b]), where b is my variable and d is a pamater in (0,1].

When I try to sovle this I get a message "Warning, solutions may have been lost" and from the official maple website they suggest to reformulate the problem.

Is there anything I can do to solve the above inequality?
