  3. Rounding - Wikipedia

    en.wikipedia.org/wiki/Rounding

    A rounding method should have utility in computer science or human arithmetic where finite precision is used, and speed is a consideration. Because it is not usually possible for a method to satisfy all ideal characteristics, many different rounding methods exist.

  4. Front-end loading - Wikipedia

    en.wikipedia.org/wiki/Front-end_loading

    Front-end loading (FEL), also referred to as Front End Planning (FEP), pre-project planning (PPP), feasibility analysis, conceptual planning, programming/schematic design and early project planning, is the process for conceptual development of projects in processing industries such as upstream oil and gas, petrochemical, natural gas refining, extractive metallurgy, waste-to-energy ...

  5. Software development effort estimation - Wikipedia

    en.wikipedia.org/wiki/Software_development...

    Formal estimation model: The quantification step is based on mechanical processes, e.g., the use of a formula derived from historical data. Combination-based estimation: The quantification step is based on a judgmental and mechanical combination of estimates from different sources. Below are examples of estimation approaches within each category.

  6. Estimation statistics - Wikipedia

    en.wikipedia.org/wiki/Estimation_statistics

    Estimation statistics, or simply estimation, is a data analysis framework that uses a combination of effect sizes, confidence intervals, precision planning, and meta-analysis to plan experiments, analyze data and interpret results. [1]

  7. Uncertainty quantification - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_quantification

    Uncertainty quantification (UQ) is the science of quantitative characterization and estimation of uncertainties in both computational and real world applications. It tries to determine how likely certain outcomes are if some aspects of the system are not exactly known.

  8. Front-end engineering - Wikipedia

    en.wikipedia.org/wiki/Front-end_engineering

    Front-End Engineering (FEE), or Front-End Engineering Design (FEED), is an engineering design approach used to control project expenses and thoroughly plan a project before a fix bid quote is submitted. [1] It may also be referred to as Pre-project planning (PPP), front-end loading (FEL), feasibility analysis, or early project planning.

  9. Randomized rounding - Wikipedia

    en.wikipedia.org/wiki/Randomized_rounding

    In computer science and operations research, randomized rounding [1] is a widely used approach for designing and analyzing approximation algorithms. [ 2 ] [ 3 ] Many combinatorial optimization problems are computationally intractable to solve exactly (to optimality).
