The Best Way To Do Something, Is Start Doing It.

You are welcome to my cosmos where visitors will observe a blend of advanced technology, specifically Artificial Intelligence and Data Mining, with strategic human behavior applicable to e-business, digital marketing, and sustainable aquaculture.

Hello, I am Dimitris Constanine Gkikas (D.C. Gkikas).

I am an Informatics Engineer with a strong interest in Artificial Intelligence applications in e-business and e-commerce analytics. Alongside my professional activities, I am a nature enthusiast and an active sportsman. From an early age, my interests have revolved around technology, marine life, and sport, complemented by a passion for music, photography, and visual arts. I maintain a strong personal commitment to environmental protection and animal welfare.

Professionally, I am an experienced Informatics Engineer specializing in the design and application of Artificial Intelligence and data mining models for e-business, e-commerce, digital and hotel marketing, risk management, and the bioeconomy. I have more than ten years of experience as a Lecturer, Postdoctoral Researcher, and e-Business Strategy Consultant in digital business development, data-driven marketing strategy, project management, and advanced analytics.

My academic and professional work focuses on predictive analytics, machine learning, and user behavior modeling to enhance digital marketing performance and support evidence-based decision-making. I combine technological expertise with marketing strategy and consumer psychology to deliver measurable growth, innovation, and competitive advantage across complex digital ecosystems. My research and applied work span e-commerce analytics, online consumer behavior, user experience, data insights, search engine optimization (with emphasis on organic performance), web design, and social media performance in both business and academic environments.

I currently serve as a Lecturer (Collaborating Academic Staff – Σ.Ε.Π.) at the School of Social Sciences of the Hellenic Open University, where I independently teach the course unit “E-Business and New Technologies for Entrepreneurship” (DEO45), with a focus on e-commerce and digital business models. In parallel, I am a Postdoctoral Researcher at the School of Agricultural Sciences, University of Patras, conducting interdisciplinary research at the intersection of artificial intelligence, predictive marketing analytics, risk analysis, digital ecosystems, and fisheries-related businesses.

In addition, I work as E-Business Development Manager at OWEB Digital Experience, overseeing e-business development, B2B operations, strategic partnerships, e-commerce strategy, and innovation initiatives.

I am an active member of EuAI, EETN, EMAC, and ELAM.

There is no easy walk to freedom anywhere, and many of us will have to pass through the valley of the shadow of death again and again before we reach the mountaintop of our desires.

Well,

Since you have been able to come this far to see this photo it means a lot!
It means that you are here, NOW. You are alive, your life goes on and you must appreciate it.
It means that your life has brought you to this moment, to this day, to this situation. Since you have managed to come so far, you are about to witness greater days.
It means that all the other lives you could possibly have lived have been erased either by accident, by choice, by chance or something Greater.
There are numerous factors that determine your future. You can only affect a small portion of these factors. However, you must DO YOUR BEST.

You are left with this life. You are here for a reason. Don't waste it. Make the best decisions!

Some people, including scientists, think that our choices shape our lives.
We make billions of decisions throughout our lifetime. So how likely is it that you’ll end up in the exact same place, with the same job and thoughts, all over again?

I'd say it's very unlikely—maybe even impossible.

The soccer paradox; I still don’t get how football fans say things like, “We won 3-0, but it could be 4-0 if we’d scored that penalty.”. By the time the ball gets into the goalkeeper's net, it has changed course and it would never be at the same position for the next goal..

Life doesn’t work that way. Every choice changes something, and every moment depends on what came before.

So, what are the factors that affect our decisions and how we can have greater impact on our lives?
Unlike chess where the rules, moves and domain are finites, human action domain is infinite!

Using Artificial Intelligence scientists try to define what can be defined. Weighted information, factors, sets of rules, classification, optimization, clusters and associated data are some of the pieces of the puzzle.

Through a series of various artificial intelligence, machine learning, SERPs, SEO, social media marketing, risk analysis and AI ethical perspectives, I try to break down technology meanings and concepts.

Stay tuned!

The Way We Search Defines The Way We Live

Traveling Salesman Problem - A Lifechanging Game

Find The Best Possible Option

Given a list of objectives and the efforts needed between each one of the objectives, what is the shortest possible effort that is needed to accomplish each objective?

The Traveling Salesman Problem (TSP) is a mathematical problem that asks the question: "Given a list of cities and the distances between them, what is the shortest possible route that visits each city exactly once and returns to the starting city?"

The TSP is a classic example of a combinatorial optimization problem, and its solution has important practical applications in fields such as transportation, logistics, and manufacturing.

The concept of the TSP can also be applied metaphorically to the way we approach problem-solving and decision-making in our daily lives. Just as the TSP asks us to find the most efficient route between multiple points, our approach to searching for information and solutions can shape the way we navigate our lives.

If we approach problems with a narrow, linear mindset, we may miss out on alternative perspectives and creative solutions. Conversely, if we approach problems with an open-minded, exploratory mindset, we may discover unexpected connections and possibilities.

In this sense, the TSP serves as a reminder that the way we search defines the way we live, and that the paths we choose can have a significant impact on the outcomes we achieve.
