| Research Type | Theoretical | We prove that given a Bn,p distribution characterized by some p (0, 1/3] {1/2}, then an evolutionary mechanism that relies on the basic mutation mechanism of a (1+1) evolutionary algorithm converges efficiently, with high probability, to an ε-optimal hypothesis. Furthermore, for 0 < α 3/13, a slight modification of the algorithm, with a uniform setup this time, evolves with high probability an ε-optimal hypothesis, for every Bn,p distribution such that p [α, 1/3 4α/9] {1/3} {1/2}. Our second contribution is that we provide a new characterization of the fitness landscape under the Bernoulli(p)n distributions Bn,p that we explore (where p (0, 1/3] {1/2}) and it is this new characterization that allows us to prove convergence using a fitness-level technique. |

| Pseudocode | Yes | Algorithm 1: The (1+1) Evolutionary Algorithm; Algorithm 2: Mutator function of the (1+1) EA for Bernoulli(p)n product distributions.; Algorithm 3: Mutator so that the (1+1) EA converges with a uniform setup for a class of Bn,p distributions. |
| Open Source Code | No | The paper focuses on theoretical analysis and algorithmic proofs for evolutionary mechanisms. There are no statements or links indicating that source code for the described methodologies is openly available or provided in supplementary materials. |
| Open Datasets | No | The paper analyzes evolvability under theoretical distributions such as 'Bernoulli(p)n distributions' and the 'uniform distribution Un'. It does not refer to or use any empirical, publicly available datasets for experimental validation. |
| Dataset Splits | No | As a theoretical paper focusing on algorithmic analysis under probability distributions, it does not involve empirical datasets or their splitting into training, validation, or test sets. |
| Hardware Specification | No | The paper is a theoretical study on evolutionary algorithms and their evolvability. It does not describe any experimental setups that would require specific hardware, and thus no hardware specifications are mentioned. |
| Software Dependencies | No | The paper presents theoretical algorithms and their analysis, rather than an implementation. Consequently, it does not specify any ancillary software or library names with version numbers required to reproduce experiments. |
| Experiment Setup | No | The paper provides a theoretical analysis of evolutionary algorithms, including proofs and lemmas. It does not include details of an empirical experimental setup such as hyperparameters, model initialization, or training schedules. |
