Capital Games and Growth Equilibria
We examine formal games that we call "capital games" in which player payoffs are known, but their payoffs are not guaranteed to be von Neumann-Morgenstern utilities. In capital games, the dynamics of player payoffs determine their utility functions. Different players can have different payoff dynamics. We make no assumptions about where these dynamics come from, but implicitly assume that they come from the players' actions and interactions over time. We define an equilibrium concept called "gr…

Glad to see someone is at least trying to address the transmission capacity problem.
Last year I worked on a project with one of Oregon’s utilities related to optimizing the use of available transmission capacity, because there just isn’t enough.

So I hacked my way into being Cyber Policy Initiative Senior Fellow at the University of Chicago's Harris School of Public Policy. I'm workin on rural water critical infrastructure cybersecurity.
Do you even hack utilities? Please chat w me. I need to quickly find out where I"m wrong about some of my assumptions.
Still very entertained by the fact that I *finally* got into the University of Chicago. :D

Plus what I thought was another telegraph pole, maybe an end pole, near the left of the photo, although I don't see cables from there to the central pole.

I really just want a few CLI utilities that essentially present what Puppet resources does as a command.

Nothing more, just: package, user, service, exec
Ideally with no dependencies like Ruby
Seems like a lot to ask alas.

Neighbors with solar panels can now trade energy directly with each other, thanks to a breakthrough cloud-based system from Washington State University.
The platform lets communities share power locally, cutting energy costs by up to 12% in testing. It's a glimpse of how neighborhoods could become mini power grids, keeping solar energy local instead of sending it back to utilities.

Community-based energy trading system for home solar-plus-storage
A research team led by Washington State University has developed a cloud-based system for trading and sharing energy from solar panels and batteries within a neighbourhood. The concept displayed potential energy cost savings of around 12% over a five-day test period.

Local. Elections. Matter.
In my city we have a vote today to push back against overreach by the state into local governance. There are just over 75,000 eligible voters.
Gainesville folks - take time today to tell the state to stay out of local governance. Vote Yes for Local Public Utilities.

Today we had the first day of the Koha DACH Hackfest in Göttingen. After a tour through the data center we started various discussions on Koha. The first feature that was requested was something I actually implemented some time ago (passing SQL to the ElasticSearch indexer), but failed to add to a weird wrapper script I did not know existed. Which I primptly fixed:

ARUQULA -- An LLM based Text2SPARQL Approach using ReAct and Knowledge Graph Exploration Utilities
Interacting with knowledge graphs can be a daunting task for people without a background in computer science since the query language that is used (SPARQL) has a high barrier of entry. Large language models (LLMs) can lower that barrier by providing support in the form of Text2SPARQL translation. In this paper we introduce a generalized method based on SPINACH, an LLM backed agent that translates natural language questions to SPARQL queries not in a single shot, but as an iterative process of e…

"Für jede Trafostation eine LEG" [‘A local energy community for every transformer station’]
It is fascinating how local energy communities are encouraged in Switzerland (so not governed by EU law, that also creates that role), and how the (local) utilities are also actively involved in this.

There were 20 or so cars at my local election precinct this evening when I drove by. Our Georgia ballot is thin, with a couple of local issues and the relatively obscure state public utilities commission.
Voters are stirred up. This is a good thing. Early voting turnout has been unusually strong.

Mean-Field Price Formation on Trees
In this work, we combine the mean-field game theory with the classical idea of binomial tree framework, pioneered by Sharpe and Cox, Ross & Rubinstein, to solve the equilibrium price formation problem for the stock. For agents with exponential utilities and recursive utilities of exponential type, we prove the existence of a unique mean-field equilibrium and derive an explicit formula for equilibrium transition probabilities of the stock price by restricting its trajectories onto a binomial tre…

Situationally Aware Rolling Horizon Multi-Tier Load Restoration Considering Behind-The-Meter DER
Restoration in power distribution systems (PDSs) is well studied, however, most existing research focuses on network partition and microgrid formation, where load transfer is limited to adjacent feeders. This focus is not practical, as when adjacent feeders lack sufficient capacity, utilities may request support from more distant feeders in practice. Such a hirarchical restoration is complex, especially when involving changing system conditions due to cold load pickup and delayed reconnection o…

KTBox: A Modular LaTeX Framework for Semantic Color, Structured Highlighting, and Scholarly Communication
The communication of technical insight in scientific manuscripts often relies on ad-hoc formatting choices, resulting in inconsistent visual emphasis and limited portability across document classes. This paper introduces ktbox, a modular LaTeX framework that unifies semantic color palettes, structured highlight boxes, taxonomy trees, and author metadata utilities into a coherent system for scholarly writing. The framework is distributed as a set of lightweight, namespaced components: ktcolor.st…

The Theory of Strategic Evolution: Games with Endogenous Players and Strategic Replicators

Abstract: This paper develops the Theory of Strategic Evolution, a general model for systems in which the population of players, strategies, and institutional rules evolve together. The theory extends replicator dynamics to settings with endogenous players, multi level selection, innovation, constitutional change, and meta governance. The central mathematical object is a Poiesis stack: a hierarchy of strategic layers linked by cross level gain matrices. Under small gain conditions, the system admits a global Lyapunov function and satisfies selection, tracking, and stochastic stability results at every finite depth. We prove that the class is closed under block extension, innovation events, heterogeneous utilities, continuous strategy spaces, and constitutional evolution. The closure theorem shows that no new dynamics arise at higher levels and that unrestricted self modification cannot preserve Lyapunov structure. The theory unifies results from evolutionary game theory, institutional design, innovation dynamics, and constitutional political economy, providing a general mathematical model of long run strategic adaptation.
