Research Type Theoretical We show that a simple randomized rounding method provides a constant-factor approximation if the optimal increase is sufficiently large, specifically, if OPT − λmin(M) = Ω(R ln k), where OPT is the optimal value, and R is the maximum trace of an augmentation matrix. To establish the guarantee, we derive a matrix concentration inequality that is of independent interest. ... Finally, we plan to explore the empirical approximation performance of simple randomized rounding through a computational study.

Pseudocode No The paper describes a 'simple randomized rounding method' and its theoretical analysis, but it does not present this method or any other procedure in a structured pseudocode or algorithm block.
Open Source Code No Finally, we plan to explore the empirical approximation performance of simple randomized rounding through a computational study.
Open Datasets No The paper discusses theoretical problems like 'Bayesian E-optimal design' and 'maximum algebraic connectivity augmentation problems' as applications, which involve general problem formulations (e.g., 'design points x1, . . . , xm Rn'). It does not, however, conduct experiments using specific, named datasets nor provide access information for any such datasets.
Dataset Splits No The paper is theoretical and does not describe experiments that would involve dataset splits.
Hardware Specification No The paper focuses on theoretical derivations and proofs; therefore, no hardware specifications for experiments are mentioned.
Software Dependencies No The paper is theoretical and does not describe experiments that would require specific software dependencies with version numbers.
Experiment Setup No The paper presents theoretical results, including a matrix concentration inequality and an approximation guarantee for a randomized rounding method. There are no experimental results, and thus no details on experimental setup or hyperparameters are provided.
