Let $V = R^{d}$ and $(x_{i}, y_{i})_{1 \leq i \leq n} \in (V \times {- 1, 1})^{n}$
Let $C = {(w, b) \in V \times R : 1 - y_{i} (w^{t} x_{i} - b) \leq 0, \forall i \in [1, n]}$
Show that $m i n_{(w, b) \in C} | | w | |^{2}$ has a solution $(w, b)$
What I tried:
$| | w | |^{2}$ is clearly continuous, I proved that C is closed. If C is bounded, then C is compact and the solution exists (In this case, I don't know how to prove that C is bounded). If C is not bounded, I don't know how to conclude either.

Consider a NLP $min {f (x) : g (x) \leq 0}$ . There are no equality constraints. The problem is feasible for small steps $t > 0$ . I have to prove that $g (x + t d) \leq 0$ if $g (x) < 0$ , where $t$ is the step length and $d$ is the direction of the line search (gradient descent).
I was thinking that since $t$ is positive and the direction $d$ can not be negative (not too sure about this fact), hence their multiplication is positive. The only way for $g (x + t d)$ to be 0 or negative is for $g (x)$ to be negative.

I have a knapsack problem
$\begin{aligned} max_{x \in {0, 1}^{n}} \sum_{i = 1}^{n} v_{i} x_{i} \\ s.t. \sum_{i = 1}^{n} w_{i} x_{i} \leq c . \end{aligned}$
The Lagrangian relaxation is as follows
$\begin{aligned} min_{λ \geq 0} max_{x \in {0, 1}^{n}} \sum_{i = 1}^{n} v_{i} x_{i} - λ (\sum_{i = 1}^{n} w_{i} x_{i} - c) . \end{aligned}$
Suppose I solved the relaxed problem and got an optimal $x_{l a g}$ s.t. $f (x^{}) < f (x_{l a g})$ where $x^{}$ is the optimal solution of the original problem and $f$ is the objective function. Even though $x_{l a g}$ gives a strict bound, is it consideblack to be a good approximate solution?
Is it true that the relaxation can be solved in polynomial time since the dual problem is convex in $λ$ and the maximization part with fixed $λ$ is just activating $x_{i}$ associated with the largest term $(v_{i} - λ w_{i})$ ?

Optimization in calculus stands for the process where you aim to find the maximum and minimum values by the provided constraints. This is exactly where the calculus is implemented. You may either go with the equations or the word problem as most answers do. The trick is to find the maximum profit for something or the minimum time it will take to complete an operation. It’s what makes optimization in calculus so important. See several answers that are provided below to use the data as the template for your assignment. It will help you t find the most efficient solutions.
