== [[Lagrangean duality|Lagrangian duality]] ==
* Author list, sections and TOC
*# Section titles should not be "bold". Please double check using source editor and avoid HTML formatting on the section titles.
*# Remove cornell ID from Author list
* An introduction of the topic
*# This section includes sentences on constructing the dual problem and is referred to as Lagrangian relaxation (LR). This is incorrect, please fix the definition of LR.
*# Definitions of LR and its relation to duality should be double checked and re-written.
*# Only one reference is present in this section. Please add more relevant references by expanding this section.
*# Consider merging the “introduction” and “history” sections.
*# In the titles, please change the font from bold to normal to have consistent formatting in the site.
* Theory, methodology, and/or algorithmic discussions
* Theory, methodology, and/or algorithmic discussions
*# The Lagrangian variables associated with equality constraints h(x) are unbounded but the Lagrangian dual problem states them as non-negative. Please fix the same.
# The Lagrangian variables associated with equality constraints h(x) are unbounded but the Lagrangian dual problem states them as non-negative. Please fix the same.
*# Also to construct a dual, we do not change minimization to maximization directly. We observed such things in the examples in lecture notes due to simplification. The lagrangian dual problem would be minimize (,).
*# Adding to the previous point, the Lagrangian is a lower bound on the original objective; the solution to the primal and dual or only equivalent if the duality gap is 0. You reference this in one section, but this is after your statement “Hence, solving the dual problem, which is a function of the Lagrangian multipliers (𝜆*) yields the same solution as the primal problem, which is a function of the original variables (x*). “. Please clarify the specific conditions that must hold for the solution of the dual to be equal to the primal’s.
*# You refer to the “Complementary Slackness Theorem”, but don’t actually write the mathematical representation of complementary slackness. Please fix this. Also consider including the derivation of the complementary slackness condition, as it is both easy and short. Boyd is a good reference for this.
*# Last step of the “process” subsection also needs updating according to the previous comments.
*# The inline notations should also be typed using LaTex.
*# Please use the LaTex code or equation editor for min, s.t., etc.
* At least one numerical example
*# Only one dual variable is associated with each constraint. The numerical example uses two for the first and second constraint which is unnecessary. Please update it accordingly for both constraints. This particular example will only have two dual variables instead of the five dual variables used currently.
*# All consecutive steps need to be updated since the dual variables would be updated.
*# After substitution the nonlinear function should be further simplified. The current expression reads like a highly nonlinear function but can be easily simplified.
*# Similar to the comments in the methodology section, inverting minimize to maximize is incorrect. Please update the dual objective function accordingly.
*# Please use the LaTex code or equation editor for min, s.t., etc.
* A section to discuss and/or illustrate the applications
*# Bullet points could be used to state the last four real-world examples that explain the physical meaning of the primal and dual problems.
*# Add references for the last set of applications.
* A conclusion section
*# This section contains a few typos. Please fix the same.
* References
*# Some citations' hyperlinks are displaying.

# No citations are present in this section.
# “mixed-integer programming (MIP)” should be used instead of “multiple integer programming (MIP)”. Please fix this error.
* Theory, methodology, and/or algorithmic discussions
*# The abbreviation MILP is not previously defined. Please fix this issue.
*# You consistently use the negative sign instead of the NOT operator for y (-y instead of ¬y).
*# Some inconsistencies with the spacing of variables, constraints, etc., under the “General” section that need to be fixed.
*# Typo in “This is shown below by M1, M2, y1, and y1:” where y1 needs to be changed to y2. Why use two different Big-M variables here? Elsewhere in the Wiki you only use one so this could lead to confusion with a general audience. Also if this was taken from the lecture notes then it needs to be cited.
* At least one numerical example
* At least one numerical example
*# Please reformulate and solve a complete numerical example rather than just reformulating a general example. Demonstrate the use of Big-M and Convex Hull formulation in an optimization problem that provides details such as individual steps in the problem solving process and final results.

== [[Sparse Reconstruction with Compressed Sensing|Sparse reconstruction with Compressed Sensing]] ==
== [[Chance-constraint method|Chance constraint method]] ==
This Wiki needs a significant rewrite. Please go through the comments for details.

*# Remove cornell id
* An introduction of the topic
*# The introductory sentence should be rephrased. The action of minimizing the risks does not inherently maximize the gains, rather PO aims to maximize gains whilst minimizing risks.
*# Amount of whitespace can be reduced by changing the orientation of Figure 1 and the sentences in this section.
*# Define terms such as risk, return, portfolio, etc., when you introduce them. Assume that the reader may not know much about finance. This goes for all other sections as well.
* Theory, methodology, and/or algorithmic discussions
* Theory, methodology, and/or algorithmic discussions
*# A brief mention of modern portfolio theory (i.e.. Markowitz) would be appropriate in this section.
# Acquisition function figure could be made larger and clearer to improve readability.
*# Several grammatical errors here involving sentence structure and clarity. Some questionable semantics (e.g., “The portfolio optimization mainly assumes two directions.”) and syntax (phrases such as “.. is as follows” should be followed by a colon). Misuse of commas and missing commas in this section. Two sentences introducing E(rp) and w should be combined into one.

== [[Bayesian Optimization | Bayesian Optimization]]  ==
* Contents: Subheadings for EI and the algorithm should not be bolded, Random words should not be capitalized.
* Author list: Remove cornell ID, Please check names
* Introduction
*# The introduction is too general and not substantial enough. For example, simply saying BayesOpt is useful when the objective function is unknown obscures exactly HOW it is useful (namely, computational efficiency in applications where ground truth sampling is expensive). Discussion on applications should be moved to a separate section.
*# Machine learning rarely includes black-box functions to be optimized. Bayesian optimization is almost never used for optimizing ML loss functions but can instead be used for hyperparameter optimization. Please update such claims in this section.
* Theory, methodology, and/or algorithmic discussions
*# Captions need reformatting.
*# Consider italicizing keywords rather than bolding.
*# Please add a citation to the first sentence.

*# Avoid pronouns such as “we”.
*# Please write equations in the Wiki instead of attaching images for equations.
*# Acquisition function figure could be made larger and clearer to improve readability.
* At least one numerical example
*# Any references to functions or methods in code ‘e.g. fmin’ should be properly formatted as code-stylized text.
*# Please use the equation editor for min, st., etc.
*# Avoid including a figure of the code for this example and explicitly describe the steps to the modeling and solution process instead.
*# Avoid pronouns such as “our” and “we”.
* A section to discuss and/or illustrate the applications
* A conclusion section
*# Please do not use brackets to enclose lists.
*# Some claims here should be supported by references. Please cite each source after its sentence.

* An introduction of the topic
*# The current introduction to the jobshop scheduling problem has only two sentences in addition to the parameter description. Introduction typically contains information about the problem, its importance in the real-world, and some information about the solution techniques and their types to solve the problem. Please add some information that covers the above.
* Theory, methodology, and/or algorithmic discussions
* Theory, methodology, and/or algorithmic discussions
*# It is unclear whether the assumptions stated in this section are required to apply the following solution techniques. Please clarify the same. Also use complete sentences to state them.
*# The branch and bounds method described in this section only discusses the solution technique for problems with one machines. However, branch and bound is a general technique that can be applied to any MILP problems with varying scales. Please update the “methods” section to be as general as possible.
*# Since this Wiki focuses on jobshop scheduling, at least two methods are expected. Branch and bound is a general MILP technique, so, it is recommended to add a tailored technique that can only solve specific jobshop scheduling problems. Solving the numerical example with this technique is not necessary.
*# Reference to the branch and bound technique described in this section is a “youtube” video. Please add references in literature that describe this method in detail. The method used in this video is highly tailored for a single machine application. This is also an incorrect way to cite a reference. Please keep this section as general as possible.
*# Use LaTex code or equation editor to display all equations and variables in this section and all other sections as well.
*# Check grammar in this section. For example, phrases like “are as follows” need to be followed by a colon and not a period.
*# Consider rewriting the assumptions as a list in this section.
* At least one numerical example
*# The example used in this section is exactly the same as the one in the youtube video. Please use a modification of this example or choose another example/method to demonstrate the solution technique.
*# The figure in this section is not numbered when all others are. Relabel this figure for consistency and its number to refer to it in-text.
* A section to discuss and/or illustrate the applications
*# This section should only focus on real-world applications of the jobshop scheduling problem. But currently, this section includes additional information on solution techniques/complexity that is appropriate for the Introduction section. Please discuss the applications of the problem in this section.
* A conclusion section
*# The meaning of  “Operations applications” is unclear. Please explain or update if necessary.
*# The current conclusion section does not properly summarize the problem. Please refer to other Wiki examples for an idea to update the section accordingly.
