The Strategy Game: A Scientific View
ResearchGate
The Strategy Game is where the art of planning meets the decision of execution. The modern term strategy can probably be attributed to Count Guibert, a French military thinker in 1799. Throughout history, we have amassed over two thousand years of literature covering strategic thinking. That literature is continuously expanding. Therefore, we decided to select a subset of ideas to help understand what happens under the strategic hood (or bonnet) —how are strategies made? We hope this document…

We hope this document provides valuable insight for people new to the subject and allows others to understand some mechanical processes. It is about thinking.

Intelligence primer - 3rd Edition
ArXiv
We started this project in 2020 to help demystify intelligence. We observed confusion and a general overuse of the term, so we explored the fundamental concepts. Technology has advanced significantly during this short period to compel us to create a 3rd Edition. These fast advancements in Artificial Intelligence may mark the start of a new human-triggered Anthropocene era, similar to the Atomic age due to the Trinity Atomic Bomb or the Industrial Revolution age due to the invention of the…

Technology has advanced significantly during this short period to compel us to create a 3rd Edition. These fast advancements in Artificial Intelligence may mark the start of a new human-triggered Anthropocene era, similar to the Atomic age due to the Trinity Atomic Bomb or the Industrial Revolution age due to the invention of the Newcomen Atmospheric Engine. Does Artificial Intelligence open another Pandora’s box [69]? Ethical con- cerns are on the rise as Artificial Intelligence increases in capability, which brings us back to our original question what is intelligence?

Algorithms are becoming more capable, and with that comes hic sunt dracones (here be dragons). The term symbolizes areas beyond our known maps. We use this term since we are stepping into an exciting, potentially dangerous, and unknown area with algorithms. Our curiosity to understand the natural world drives our search for new methods.

The term symbolizes areas beyond our known maps. We use this term since we are stepping into an exciting, potentially dangerous, and unknown area with algorithms. Our curiosity to understand the natural world drives our search for new methods. For this reason, it is crucial to explore this subject.
The project's objective is to overlay the information obtained, in conjunction with the state of hardware today, to see if we can determine the likely directions for future algorithms'. Even though we slightly cover non-classical computing in this paper, our primary focus is on classical computing (i.e., digital computers). It is worth noting that non-classical quantum computing requires classical computers to operate; they are not mutually exclusive... -
Learning the techniques to solve problems
ResearchGate
This short document is about learning the techniques to solve problems. I will try to highlight the essential levers and pulleys available. Everyone has their approach to handling problems. The ideas presented here come from my own experiences and the experiences of far more talented people (e.g., Richard Hamming, George Polya, and John Cleese, to name a few).

Genetic Improvement in the Shackleton Framework for Optimizing LLVM Pass Sequences
arXiv
Genetic improvement is a search technique that aims to improve a given acceptable solution to a problem. In this paper, we present the novel use of genetic improvement to find problem-specific optimized LLVM pass sequences. We develop a pass-level patch representation in the linear genetic programming framework, Shackleton, to evolve the modifications to be applied to the default optimization pass sequences. Our GI-evolved solution has a mean of 3.7% runtime improvement compared to the -O3…
Genetic improvement is a search technique that aims to improve a given acceptable solution to a problem. In this paper, we present the novel use of genetic improvement to find problem-specific optimized LLVM pass sequences. We develop a pass-level patch representation in the linear genetic programming framework, Shackleton, to evolve the modifications to be applied to the default optimization pass sequences. Our GI-evolved solution has a mean of 3.7% runtime improvement compared to the -O3 optimization level in the default code generation options which optimizes on runtime. The proposed GI method provides an automatic way to find a problem-specific optimization sequence that improves upon a general solution without any expert domain knowledge. In this paper, we discuss the advantages and limitations of the GI feature in the Shackleton Framework and present our results.

Optimizing LLVM Pass Sequences with Shackleton: A Linear Genetic Programming Framework
Arxiv
In this paper we introduce Shackleton as a generalized framework enabling the application of linear genetic programming -- a technique under the umbrella of evolutionary algorithms -- to a variety of use cases. We also explore here a novel application for this class of methods: optimizing sequences of LLVM optimization passes. The algorithm underpinning Shackleton is discussed, with an emphasis on the effects of different features unique to the framework when applied to LLVM pass sequences…
In this paper we introduce Shackleton as a generalized framework enabling the application of linear genetic programming -- a technique under the umbrella of evolutionary algorithms -- to a variety of use cases. We also explore here a novel application for this class of methods: optimizing sequences of LLVM optimization passes. The algorithm underpinning Shackleton is discussed, with an emphasis on the effects of different features unique to the framework when applied to LLVM pass sequences. Combined with analysis of different hyperparameter settings, we report the results on automatically optimizing pass sequences using Shackleton for two software applications at differing complexity levels. Finally, we reflect on the advantages and limitations of our current implementation and lay out a path for further improvements. These improvements aim to surpass hand-crafted solutions with an automatic discovery method for an optimal pass sequence.

Is Expressiveness the Future of Software?
IEEE Computer
We explore what potentially may happen to software by 2033, taking views from across the industry. Our central premise is that, by increasing problem-domain expressiveness, more real-world experiences can be captured and converted into digital simulators, which can form shareable models of knowledge.

Evolution of the Semiconductor Industry, and the Start of X Law
Springer
In this paper, we explore the use of evolutionary concepts to predict what-comes-next for the Semiconductor Industry. At its core, evolution is the transition of information. Understanding what causes the transitions paves the way to potentially creating a predictive model for the industry. Prediction is one of the essential functions of research; it is challenging to get right; it is of paramount importance when it comes to determining the next commercial objective and often depends on a…
In this paper, we explore the use of evolutionary concepts to predict what-comes-next for the Semiconductor Industry. At its core, evolution is the transition of information. Understanding what causes the transitions paves the way to potentially creating a predictive model for the industry. Prediction is one of the essential functions of research; it is challenging to get right; it is of paramount importance when it comes to determining the next commercial objective and often depends on a single change. The most critical part of the prediction is to explore the components that form the landscape of potential outcomes. With these outcomes, we can decide what careers to take, what areas to dedicate resources towards and further out as a possible method to increase revenue. The Semiconductor Industry is a complex ecosystem, where many adjacent industries rely on its continued advancements. The human appetite to consume more data puts pressure on the industry. Consumption drives three technology vectors, namely storage, compute, and communication. Under this premise, two thoughts lead to this paper. Firstly, the End of Moore’s Law (EoML) [33], where transistor density growth slows down over time. Either due to costs or technology constraints (thermal and energy restrictions). These factors mean that traditional iterative methods, adopted by the Semiconductor Industry, may fail to satisfy future data demands. ...

2019 Evolutionary Algorithms Review

Evolutionary algorithm research and applications began over 50 years ago. Like other artificial intelligence techniques, evolutionary algorithms will likely see increased use and development due to the increased availability of computation, more robust and available open source software libraries, and the increasing demand for artificial intelligence techniques. As these techniques become more adopted and capable, it is the right time to take a perspective of their ability to integrate into society and the human processes they intend to augment. In this review, we explore a new taxonomy of evolutionary algorithms and resulting classifications that look at five main areas: the ability to manage the control of the environment with limiters, the ability to explain and repeat the search process, the ability to understand input and output causality within a solution, the ability to manage algorithm bias due to data or user design, and lastly, the ability to add corrective measures. These areas are motivated by today's pressures on industry to conform to both societies concerns and new government regulatory rules. As many reviews of evolutionary algorithms exist, after motivating this new taxonomy, we briefly classify a broad range of algorithms and identify areas of future research.

Parallelism and the ARM instruction set architecture
IEEE Computer
Over the past few years, the ARM reduced-instruction-set computing (RISC) processor has evolved to offer a family of chips that range up to a full-blown multiprocessor. Embedded applications' demand for increasing levels of performance and the added efficiency of key new technologies has driven the ARM architecture's evolution. Throughout this evolutionary path, the ARM team has used a full range of techniques known to computer architecture for exploiting parallelism. The performance and…
Over the past few years, the ARM reduced-instruction-set computing (RISC) processor has evolved to offer a family of chips that range up to a full-blown multiprocessor. Embedded applications' demand for increasing levels of performance and the added efficiency of key new technologies has driven the ARM architecture's evolution. Throughout this evolutionary path, the ARM team has used a full range of techniques known to computer architecture for exploiting parallelism. The performance and efficiency methods that ARM uses include variable execution time, subword parallelism, digital signal processor-like operations, thread-level parallelism, and exception handling, and multiprocessing. Leveraging parallelism on several levels, ARM's new chip designs could change how people access technology. With sales growing rapidly and more than 1.5 billion ARM processors already sold each year, software writers now have a huge range of markets in which their ARM code can be used.
