I'd like to not have to define local variables inside the function totaladj, as shown in the code that is commented out. Right now it doesn't work (unless I use the commented out code). Any help would be greatly appreciated. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/6e6ed6ad-676d-4659-8b54-8bdbddeae585 Iuval Clejan 2026-03-11T17:45:31Z https://community.wolfram.com/groups/-/m/t/3672532 ![Adiabatic quantum computing: spectral analysis and simulation of a one-qubit system][1] &[Wolfram Notebook][2] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=Adiabaticquantumcomputingspectralanalysisandsimulationofaone-qubitsystem.png&userId=20103 [2]: https://www.wolframcloud.com/obj/57c27ccc-c9d9-456a-8535-b7e58d5abb07 Sebastian Rodriguez 2026-03-31T17:00:25Z https://community.wolfram.com/groups/-/m/t/3671492 &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/1f196033-714a-413f-90e4-7b22075ea1f4 Tigran Nersissian 2026-03-30T09:44:23Z https://community.wolfram.com/groups/-/m/t/3671538 &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/42a99c2e-ce28-4d78-bda1-bea3cdd88834 Alejandro Latorre Chirot 2026-03-28T18:47:52Z https://community.wolfram.com/groups/-/m/t/3647733 &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/b04b6551-fecf-465d-b02d-63d95abd751c Tigran Nersissian 2026-03-02T11:53:13Z https://community.wolfram.com/groups/-/m/t/3655721 &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/3eb36db8-fd30-4bb0-898a-19be77d0704f Housam Binous 2026-03-09T11:25:23Z https://community.wolfram.com/groups/-/m/t/3649946 If $f:\mathbb{N}\to\mathbb{R}$ and $g:\mathbb{N}\to\mathbb{R}$ are arbitrary functions, I want to calculate this equation with Mathematica: $$\small{\begin{equation} c=\inf\left\{|1-\mathbf{c_1}|:\forall(\epsilon>0)\exists(\mathbf{c_1}>0)\forall(r\in\mathbb{N})\exists(v\in\mathbb{N})\left(\left|\frac{f(r)}{g(v)}-\mathbf{c_1}\right|<\varepsilon\right)\right\}, \end{equation}}$$ Here is what it does: To obtain $c$, we want $\mathbf{c_1}$ must satisfy the following: 1. $\mathbf{c_1}$ is positive 2. $\mathbf{c_1}$ satisfies 1. and the quantified statement in Equation 3. $\mathbf{c_1}$ satisfies 1. and 2., and has the smallest absolute difference from $1$.

I get the o/p in this case. However, I want to put a constraint that these nine variables have only positive values. How to put this constrain in form of {a, b}. According to the definition of a and b, ({a, b} is equivalent to ax+b>= 0), I should have a =1 and b = 0 for each of the nine variables. So I tried {{1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}, {1, 0}}. However it did not work. Will appreciate any suggestions. Thanks S G 2026-01-21T14:48:17Z https://community.wolfram.com/groups/-/m/t/3605493 Is this possible, that some constraints have parameters that depend on the target function? Or do the constraints need to be statable in an unchanging way?
