This document discusses two examples of applying game theory to model strategic interactions between players. The first example analyzes a game between two political parties determining campaign strategies. It finds the optimal mixed strategies that give each party an expected payoff of 61. The second example models competition between two scooter manufacturers. It finds the optimal mixed strategies for product changes that give each a 5/6 expected market share. Game theory is used to analyze strategic decisions and find equilibrium strategies in both political and business competition scenarios.
In this assignment, I was asked to create flowcharts from psuedocode and vice versa. Questions 7 and 8 required me to design a program and psuedocode from a brief description of what the program needed to do. This shows my understanding of programming logic, as well as designing flowcharts and psuedocode.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

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.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. Applications Of Game Theory…
• Example 1 (Principle of Dominance):
In an election campaign, the strategies adopted by the ruling and opposition party along
with pay-offs (ruling party's % share in votes polled) are given below:
Opposition Party's Strategies
Ruling Party's Campaign Campaign Spend two days
Strategies one day in two days in in large.
Campaign one 55 40 35
day in each city
Campaign two 70 70 55
days in large
towns
Spend two days 75 55 65
in large rural
sectors
Assume a zero sum game. Find optimum strategies for both parties and expected payoff
to ruling party.
4. Let A1, A2 and A3 be the strategies of the ruling party and B1, B2 and B3 be those of the
opposition. Then
Player B
B1 B2 B3
A1 55 40 35
Player A
A2 70 70 55
A3 75 55 65
Here, one party knows his strategy as well as other party's strategy and one person's gain is
another person's loss.
5. Now, with the given matrix:
Player B
B1 B2 B3 Row
minimax
Player A A1 55 40 35 35
A2 70 70 55 55
A3 75 55 65 65
Column 75 70 65
maxima
As maximin = 55 and minimax= 65 , there is no saddle point.
6. Row 1 is dominated by row 2 and column 1 is dominated by column 2 giving the
reduced 2 x 2 matrix as :
B2 B3
A2 70 55
A3 55 65
P= d–c
(a + c) – (b + c)
= 65 – 55
(70 + 65)- (55 + 55)
= 2
5
1-P = 1– 2
5
= 3
5
7. q = d–b
(a + d) – (b + c)
= 65 – 55
(70 + 65) – (55 + 55)
= 2
5
1–q = 3
5
v = ad – bc
(a + b) – (b + c)
= 70 * 65 – 55 * 55
25
= 4550 – 3025
25
= 61
8. By equating expected losses of opposition party, regardless of what ruling party would
choose, we get
15 q1 + 55 = -l0ql + 65 so that q1 = 2/5 and (1 – q1) = 3/5
Hence opposition party would choose strategy B2 and B3 with a probability of
0.4 and 0.6 respectively.
The value of the game is determined by substituting the value of p1 and q1 in any of the
expected values and is determined as 61, i. e.,
Expected gain to ruling party:
(i) 15 x 0.4 + 55 = 61
(ii)-10 x 0.4 + 65 = 61
Expected loss to opposition party:
(i) 15 x 0.4 + 55 = 61
(ii) -10 x 0.4 + 65 = 61
9. EXAMPLE 2.
Even though there are several manufacturers of scooters, two
firms with branch names Janta and Praja, control their market in Western India. If both
manufacturers make model changes of the same type for this market segment in the
same year, their respective market shares remain constant. Likewise, if neither makes
model changes, then also their market shares remain constant. The pay-off matrix in
terms of increased/decreased percentage market share under different possible
conditions is given below:
JANTA PARAJ
NO CHANGE MINOR MAJOR
CHANGE CHANGE
NO CHANGE 0 -4 -10
MINORCHAN 3 0 5
GE
MAJOR 8 1 0
CHANGE
10. Solution.
(i) Clearly, the game has no saddle point. Making use of dominance principle, since the
first row is dominated by the third row, we delete the first row. Similarly, first
column is dominated by the second column and hence we delete the first column.
The reduced pay-off matrix will be as follows:
PRAJA
JANTA MINOR CHANGE MAJOR CHANGE
MINOR CHANGE 0 5
MAJOR CHANGE 1 0
As the reduced pay-off matrix does not possess any saddle point, the players will use
mixed strategies. The optimum mixed strategy for player A is determined by
11. P = d– c
(a + d) – (b + c)
= 0-1
(0+0)-(5+1)
= 1
6
1-p = 1-1
6
= 5
6
q = d-b
(a + d) - (b + c)
= 0–5
(0 – 0) – (5 - 1)
= 5
6
1–q = 1–5
6
= 1
6
12. V = ad-bc
(a + d) - (b + c)
= (0 x 0) – (5 x 1)
(0 + 0) – (5+1)
= 5
