This document introduces the concept of dynamic programming and uses the knapsack problem as an example. Dynamic programming breaks large problems down into smaller subproblems that are solved just once and stored for future use, unlike divide-and-conquer which may solve subproblems multiple times. The knapsack problem involves finding the highest-value combination of items to fill a knapsack without exceeding its capacity. Dynamic programming solves this problem in linear time by calculating the optimal values for partial knapsacks up to the full capacity.

Dynamic Programming is a method for solving a complex problem by breaking it down into a collection of simpler subproblems, solving each of those subproblems just once, and storing their solutions using a memory-based data structure (array, map,etc).
Comparison of Dynamic Programming Algorithm and Greedy Algorithm on Integer K...faisalpiliang1
At this time the delivery of goods to be familiar because the use of delivery of goods services greatly facilitate customers. PT Post Indonesia is one of the delivery of goods. On the delivery of goods, we often encounter the selection of goods which entered first into the transportation and held from the delivery. At the time of the selection, there are Knapsack problems that require optimal selection of solutions. Knapsack is a place used as a means of storing or inserting an object. The purpose of this research is to know how to get optimal solution result in solving Integer Knapsack problem on freight transportation by using Dynamic Programming Algorithm and Greedy Algorithm at PT Post Indonesia Semarang. This also knowing the results of the implementation of Greedy Algorithm with Dynamic Programming Algorithm on Integer Knapsack problems on the selection of goods transport in PT Post Indonesia Semarang by applying on the mobile application. The results of this research are made from the results obtained by the Dynamic Programming Algorithm with total weight 5022 kg in 7 days. While the calculation result obtained by Greedy Algorithm, that is total weight of delivery equal to 4496 kg in 7 days. It can be concluded that the calculation results obtained by Dynamic Programming Algorithm in 7 days has a total weight of 526 kg is greater when compared with Greedy Algorithm.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

2. Introduction
• In divide and conquer principle, large problem is solved by
breaking it up into smaller problems which can be solved
independently
• In dynamic programming, this principle is carried to an
extreme
• When we do not know exactly which smaller problems to
solve, we simply solve them all, then store the answers away
to be used later in solving larger problems
3. Two Difficulties
• It may not always be possible to combine the solutions of
smaller problems to form the solution of a larger one
• The number of small problems to solve may be unacceptably
large
4. Knapsack Problem
• A thief robbing a safe finds it filled with N types of items of
varying size and value
• But has only a knapsack of capacity M to carry the goods
• The knapsack problem is to find the combination of items
which the thief should choose for his knapsack in order to
maximize the total value of all the items he takes
5. Example
• Capacity of the knapsack = 17
• Then the thief can take five A’s for a total take of 20, or he can
fill up his knapsack with a D and an E for a total take of 24
• He can try many other combinations
• But which will maximize his total take?
Size 3 4 7 8 9
Value 4 5 10 11 13
Name A B C D E
6. Dynamic Programming Solution
• We calculate the best combination for all knapsack sizes up to
M
• It turns out that we can perform this calculation very
efficiently by doing things in an appropriate order
7. The program
for (j = 1; j <= N; j++)
{
for (i = 1; i <= M; i++)
if( i >= size[j] )
if( cost[i] < cost[i – size[j]) + val[j] )
{
cost[i] = cost[i – size[j]] + val[j];
best[i] = j;
}
}
8. Details
• cost[i] is the highest value that can be achieved with a
knapsack of capacity i
• best[i] is the last item that was added to achieve that maximum
• cost[0] = 0
i 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
cost[i] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
best[i]
9. Contents of the Optimal Knapsack
• The actual contents of the optimal knapsack can be computed
with the aid of the best array
• By definition, best[M] is included
• The remaining contents are the same as for the optimal
knapsack of size M – size[best[M]]
• Therefore best[M – size[best[M]]] is included, and so forth
10. For Our Example
• First, best[17] = C
• Then we find another type-C item at size 10
• Then a type-A item at size 3
11. Conclusions
• The dynamic programming solution to the knapsack problem
takes time proportional to N * M
• The knapsack problem is easily solved if M is not large
• But the running time can become unacceptable for large
capabilities
• This method does not work at all if M and the sizes or values
are, for example, real numbers instead of integers
