Literature review
This section will give a summary of the conventional approaches to software source code generation (SSCG), a review of the literature on AI advances applied to ASSCG, and a quick analysis of the effects of AI on ASSCG.

Traditional methods of (SSCG).
Traditional methods of software source code generation have been foundational to the evolution of software engineering practices.These methods typically involve manual coding by developers using text editors or integrated development environments (IDEs).For example, Hand Coding requires deep knowledge of both the chosen programming language (C, Java, Python, etc.) and the specific problem they were solving.This approach, while foundational, can be time-consuming and error-prone.Copy-Pasting: In situations where similar functionality is required in multiple parts of a project, developers may resort to copy-pasting existing code snippets and making necessary modifications.While this approach can save time, it often leads to code redundancy and maintenance issues.Code Templates [2]: Another traditional method involves the use of code templates or boilerplate code provided by IDEs or libraries.Developers can use these templates as a starting point and customize them according to their requirements.However, this method still requires manual intervention for adaptation and customization.Code Generators: Some traditional software development environments include code generators that automate the generation of repetitive or boilerplate code.These generators may be built into the IDE or provided as separate tools.They typically operate based on predefined templates or rules provided by the developer [3][4].Scripting: In certain cases, developers may employ scripting languages or scripting tools to automate specific tasks within the software development process.These scripts can automate repetitive tasks, such as file manipulation, data processing, or code generation based on certain criteria.Manual Refactoring [5]: When existing code needs to be optimized or modified to improve readability, performance, or maintainability, developers may engage in manual refactoring.This involves restructuring existing code without changing its external behavior, often to make it more efficient or easier to understand.
While these traditional methods have been instrumental in software development for decades, they are often labor-intensive, error-prone, and timeconsuming.With the emergence of ASSCG techniques, there has been a shift towards leveraging AI and machine learning to streamline and enhance the code generation process, leading to increased efficiency and productivity in software development.

Related works
A range of AI techniques have been applied to ASSCG, each with its own strengths and weaknesses.Yen [6] proposed the use of AI planning techniques to synthesize glue code and automate testing, while Cruz-Benito [7] compared the performance of different deep learning architectures in generating code.Danilchenko [8] introduced a system that combined Case-Based Reasoning, Routine Design, and Template-Based Programming [8] for ASSCG, and Dehaerne [5] provided a systematic review of studies using machine learning for code generation, highlighting the use of recurrent neural networks, transformers, and convolutional neural networks.These studies collectively demonstrate the potential of AI in code generation, with each approach offering unique contributions and considerations.While rule-based methods like Koziolek et al.'s [9] in industrial automation shine in reliability and predictability, their rigidity can pose challenges for handling complex, non-standardized tasks.Meanwhile, natural language processing (NLP) integration, as highlighted by Zhu and Shen's [10] work on natural language to code generation, unlocks exciting possibilities but necessitates models attuned to the intricate context of software development language.Finally, evolutionary algorithms, exemplified by Mironovich et al.'s [11]work on function block applications, offer a unique approach to optimizing code but face scalability concerns and limitations in real-time scenarios.Recent research has focused on the use of deep learning in programming language models, particularly for tasks such as auto-completion and code generation.Cruz-Benito (2020) [8] compares different neural network architectures, including AWD-LSTMs, AWD-QRNNs, and Transformer, for building language models using a Python dataset.The study highlights the strengths and weaknesses of each approach and identifies gaps in evaluating and applying these models in a real programming context.Le [12] offers a thorough analysis of the deep learning techniques currently in use for generating and modeling source code, categorizing program learning tasks and discussing the challenges and recommendations for practitioners and researchers.These studies collectively underscore the potential of deep learning in software engineering and the need for further research in this area.Another area of focus is the automatic generation of source code comments, with a survey of algorithms and techniques [13].Finally, a component-based approach has been proposed for the systematic generation of correct, compatible, and efficient database structures and manipulation function modules [14].
In Table1, we provide the key findings from the surveyed literature, focusing on evaluation metrics such as accuracy, efficiency, scalability, generalization.Where these metrics values are: High: (H), Limited (Lm), Low (Lo), Moderate (M), and Conceptual: (Co).[16] and correctness not extensively studied.

Current State-of-the-Art (SOTA) techniques
This paper explores the SOTA in AI-driven Automatic Software Source Code Generation (ASSCG), examining promising techniques like Deep Learning (LSTMs and Transformers for natural language to code translation), Rule-based Methods (CAYENNE for predictable code in industrial automation), Evolutionary Algorithms (optimizing code for specific goals), and AI Planning Techniques (frameworks like STRIPS for autonomous code generation).However, limitations like limited domain specificity, accuracy, and bias, alongside interpretability challenges, remain.By analyzing a list of these techniques, and providing future research directions, this paper aims to address these limitations and promote responsible development of ASSCG, ultimately unlocking its full potential for software development.

AI Innovations for ASSCG
ASSCG has experienced remarkable advancements fueled by various AI innovations.Let's explore each of these innovations in detail: Rule-based Systems (RBS): These systems create code from high-level specifications using predetermined rules and patterns.Frequently utilized in specialized fields and industrial automation, RBS provide control and interpretability over the code that is created.[9] [17].Machine Learning (ML) Approaches: ML tools, including transformers, RNNs, and statistical language models, are trained on large code repositories to identify patterns and correlations, which allows them to produce code based on learned information.[5]  The explanation of how each innovation works and its application in generating software source code will be provided in Table 2, and some examples of applications of AI innovation in ASSCG will be listed in Table 3 4 provides a concise overview of the challenges faced in AI-driven ASSCG, along with their identification and analysis.Addressing these challenges is crucial for maximizing the effectiveness and reliability of AI-driven code generation systems.Generated code may be overly complex or difficult to maintain.
Complexity in generated code can impede collaboration, increase the risk of errors during maintenance, and hinder scalability of the codebase.Ambiguity and Natural Language Understanding [30] Extracting precise requirements from natural language can be challenging.
Natural language inputs may contain ambiguity, context-dependency, and linguistic nuances, leading to inaccuracies or misinterpretations in code generation.

Lack of Context Awareness
AI models may lack contextual understanding of code semantics and constraints.
Contextually inappropriate code generation can result in inefficiencies, inconsistencies, and compatibility issues in the generated codebase.

Ethical and Legal Considerations [31][3]
AI-driven code generation raises concerns regarding intellectual property and ethics.
Developers must navigate ethical and legal considerations surrounding ownership, licensing, and misuse of AI-generated code.

Performance and Scalability[23][32]
AI models may exhibit performance bottlenecks or scalability limitations.
Optimizing efficiency and scalability of AI-driven code generation systems is crucial for timely and cost-effective development.

Limitations
While AI-driven ASSCG offers significant benefits in terms of efficiency, productivity, and innovation, it also faces limitations related to scalability, interpretability, and handling of complex software requirements as shown in Table 5. Overcoming these l limitations requires interdisciplinary efforts, including advancements in AI research, software engineering practices, and collaboration between developers and AI systems.By addressing these limitations, developers can harness the full potential of AI-driven code generation to accelerate software development and enhance code quality and reliability.

Limitation
Description Analysis Scalability [33] While AI models may perform well on small-scale projects or specific tasks, they may encounter challenges when applied to large-scale software development projects or complex codebases.
Scaling AI code generation for large projects is difficult.It requires a lot of computing power and storage to handle the complex interactions between different code parts as the project grows.This complexity makes it hard for AI models to maintain good performance and generate accurate code.Interpretability [34] AI-generated code is like a magic trickit works, but you don't know how.This lack of understanding makes it hard for developers to trust the code and fix issues if they arise AI-generated code is like a black box -developers can't understand how it works.This makes it hard to trust the code, fix problems, and collaborate on projects using the code.
Handling of Complex Software Requirements [35] AI for code generation isn't great with complex projects.It struggles to understand the specific rules (business Current AI models for automated code generation exhibit limitations when applied to complex software development.The intricate decision-making processes logic) and specialized knowledge needed for those projects.Additionally, it has trouble with requirements that focus on things other than the code itself (nonfunctional requirements).
and interwoven functionalities inherent in such projects pose challenges for AI to capture effectively.This can result in incomplete or suboptimal code generation.Furthermore, the prevalence of edge cases and unexpected scenarios in complex software creates additional hurdles for AI to navigate.

( 2023) [22] investigated finetuning prompts for GPT-3, a powerful language model, to improve its code generation capabilities.Results: Fine-tuned prompts yielded moderate improvements in code accuracy and fluency compared to generic prompts.

Case Studies
Key takeaway: Fine-tuning large language models like GPT-3 shows promise for code generation but requires careful prompt design and further research.5) GitHub Copilot: GitHub Copilot is a tool that uses artificial intelligence to help developers write code.It can suggest code completions, generate entire functions, and even write entire programs [37].6) Google Cloud AutoML Code: It can be used to generate code for a variety of PLs and platforms [38] using ML.
These are just a few examples.The field of code generation is rapidly evolving, with new techniques and applications emerging all the time.As AI research progresses, we can expect to see even more sophisticated and efficient code generation tools in the future.
