ABRA: An algorithm which cannot converge to low-quality Nash equilibria
Vartika Singh, Philip N. Brown
We consider a game theoretic approach to solve multi-agent coordination problems with submodular objectives. It is known for such problems that the Nash equilibria for the correspo…
Truncated Noisy Best-Response Algorithms: Toward Game Theoretic Learning with Safety Guarantees
Vartika Singh, Philip N. Brown
We consider a game theoretic approach to solve multi-agent coordination problems with submodular maximization objectives. It is known for such problems that the Nash equilibria for…
Hadronic tau decays at higher orders in QCD
Gauhar Abbas, Vartika Singh
We investigate higher-order perturbative corrections to hadronic decays by applying nonlinear sequence-transformation techniques to the QCD correction . In particular,…
A new determination of higher-order QCD corrections to hadronic decays
Gauhar Abbas, Vartika Singh
We employ \textit{Levin-type sequence transformations} to accelerate the convergence of the perturbative fixed-order expansion of the QCD correction in terms of the stron…
Dark-technicolour at colliders
Gauhar Abbas, Vartika Singh, Neelam Singh
We demonstrate that QCD-like gauge dynamics can be consistently embedded within the Dark Technicolor paradigm by invoking the extended Most Attractive Channel hypothesis, thereby r…
Stability of Polling Systems for a Large Class of Markovian Switching Policies
Konstantin Avrachenkov, Kousik Das, Veeraruna Kavitha +1
We consider a polling system with two queues, where a single server is attending the queues in a cyclic order and requires non-zero switching times to switch between the queues. Ou…
Optimal Utility Design with Arbitrary Information Networks
Vartika Singh, Will Wesley, Philip N. Brown
We consider multi-agent systems with general information networks where an agent may only observe a subset of other agents. A system designer assigns local utility functions to the…
Stochastic vaccination game among influencers, leader and public
Vartika Singh, Veeraruna Kavitha
Celebrities can significantly influence the public towards any desired outcome. In a bid to tackle an infectious disease, a leader (government) exploits such influence towards moti…
Fixed-point equations solving Risk-sensitive MDP with constraint
Vartika Singh, Veeraruna Kavitha
There are no computationally feasible algorithms that provide solutions to the finite horizon Risk-sensitive Constrained Markov Decision Process (Risk-CMDP) problem, even for probl…
Fair opportunistic schedulers for Lossy Polling systems
Vartika Singh, Veeraruna Kavitha
Polling systems with losses are useful mathematical objects that can model many practical systems like travelling salesman problem with recurrent requests. One of the less studied…
Flavour bounds on the flavon of a minimal and a non-minimal symmetry
Gauhar Abbas, Vartika Singh, Neelam Singh +1
We investigate flavour bounds on the and flavour symmetries. These flavour symmetries are a minimal and a…
Renormalization-group improved Higgs to two gluons decay rate
Gauhar Abbas, Astha Jain, Vartika Singh +1
We investigate the renormalization-group scale and scheme dependence of the decay rate at the order NLO in the renormalization-group summed perturbative theo…
Evolutionary Vaccination Games with premature vaccines to combat ongoing deadly pandemic
Vartika Singh, Khushboo Agarwal, Shubham +1
We consider a vaccination game that results with the introduction of premature and possibly scarce vaccines introduced in a desperate bid to combat the otherwise ravaging deadly pa…
Asymmetric Information Acquisition Games
Vartika Singh, Veeraruna Kavitha
We consider a stochastic game with partial, asymmetric and non-classical information, where the agents are trying to acquire as many available opportunities/locks as possible. Agen…
